I work at a tire shop and we are required to apply anti-seize to all wheel studs when removing wheels. Keep into consideration that many people go years without removing their wheels which gives plenty of time for the lug nuts and studs to rust on and seize up making them difficult to remove, which we have to deal with often. We remove hundreds of wheels a week and have never had a customer's wheels loosen or fall off even after not having their tires serviced for years. Just thought I'd throw that out there.

Good engineering dictates: 1. Decide the necessary clamping force. 2. Pick a stud that when lubed with anti-sieze and torqued to X lb/ft will provide 100% of necessary clamping force at 50% of force necessary to destroy the stud. This allows for human error. But this means a bigger fastener , more $.

It’s a bit late in the day but I’ve anti seized wheel studs and bolts for 40 + years and never ever had a bolt break or loosen or a wheel fall off . On the counter side I have had wheel bolts break because they were seized in and simply either tore the threads off or twisted off the stud or made the bolt almost impossible to remove . I know exactly which is better and I’m sticking to it thanks .

So glad I stumbled upon this vid. I’ve coated my lug studs for years (since we live in the rust belt) and ran into trouble for the first time tightening our 2023 Jeep GC L lug nuts to the very high but manual required spec of 130 foot pounds. Trying to reach that spec with permatex anti-seize on the stud and lug nuts actually caused two of our studs to rotate with an inability to reach the spec. I initially thought it was a manufacturer defect. Our local Jeep dealership had to replace the entire setup. To me, the higher the torque spec, the more damage can be done if using anti-seize. Thanks again for posting.

I feel like the pros of using anti-seize outweigh the cons. I use grease, torque to spec, and re-torque after the car's been driven a good 50 miles or so. They are built so over spec, they can handle it, and they aren't going to seize. And there's no way anti-seize is getting them tight enough to warp rotors. I have seen way, way more lugnuts snap during removal than during tightening. There's also the problem of less than perfect studs and or lugnuts decreasing the load on the hub and possibly loosening over time, (I saw this happen less than a year ago on a relatives car). Anti seize will help with this problem.

Very informative and professional explanation of the phenomenon. It still leaves me with the problem of what you would do on a cold dark night in the middle of nowhere when you can't get the lug nuts loose because they have rusted on. It seems that those smart people you referred to have come up short or don't care about what may happen in the real world. Since the lubricant you used is called ANTI seize I think that it would be good practice for the engineers designing these systems to take the likelihood of seizing nuts and bolts into their calculations and provide a torque specification for users who want to avoid the possibility of seizing into account.

@EmbraceMaking

Thanks Byon Bill! The engineers definitely take this into account. I can't say for certain, but from my own experience I think it is a choice of the lesser of two evils. Although bolts that have anti-seize and the correct torque applied should theoretically not loosen off during normal use, sometimes this happens. It can be due to vibration or micro movements relative to the two parts, eventually the lugs loosen. When no anti-seize is applied, the bolts may seize a little (as you experienced) and this may prevent them from backing off. Although this is an inconvenience, it is the lesser of two evils compared to your wheel lugs falling off while you drive. Another reason I can think of is that when people apply anti-seize, it is not always uniform, the same type, on just the threads vs the threads and the underside of the bolt/nut, etc. It introduces many more variables into the equation and the friction value may not be consistent each time. Whereas dry is, well, dry. Less things to take into account so it's easier to just supply a dry torque value. That's what I can think of off the top of my head. Thanks for watching!

Byon Bill it sounds like the scenario you came up with is from just using your impact gun to put on your wheel lug nuts and not setting your gun to the one setting and barely getting them tight. Your problem may start with the person who Services your wheels. You need to torque in the air with the brakes on your your vehicle. Over torquing or putting them on with an impact. Is the real problem. There is a solution though. If you ever grab a nut with your finger and tighten it as hard as you can just barely tap it with a hammer and you will see it will move. If you need to loosen a nut that's been impacted to put on. then it needs to be impacted to take it off. just smack the tire iron or socket with a hammer as you are trying to loosen it and it will come free.

I typically torque them to the same specs as recommended and never had a lug nut come loose. But they do come loose a lot easier when you want them to. The other alternative has been broken 1/2” ratchets, sockets, and the cheesy cheap breaker bars that are included from the factory would strip and or bend.

Interesting. Ive been working in cars for over 50 years. When working on my own cars I have generally always used anti-seize on the lug nuts/bolts and have never had one problem in all that time. Also use it on any nut/bolt that I know will be needed to remove for future repairs such as the EGR valve I recently replaced. Just lucky I guess.

I use lube all the time but maybe theres a caveat . Being a professional mechanic for 30 years and hobby mechanic before and after, one tends to gain a clear sense of torque required. Cant expect everyone to develop that same sense so i can understand why some manufactures and shops set specs and guidelines. Problem is, some torques are dry, some lubed. Why not lugs lubed? It gives much more accurate torque. Ive installed many critical parts on turbine engines as well as wing bolts and spark/igniter plugs that call up a thread lube. Many others dont but on aircraft its rare to be dealing with fasteners in a environment remotely as harsh as wheel lugs.

Excellent presentation and technically accurate. I used to work for GM in tire testing and everything you said is accurate. Well done!

Very interesting video. Thanks for taking the time and effort to research/prepare and post. While I don't work on cars, I do build many and maintain all of the firearms which I own/shoot. For the AR's that I build, I regularly use anti-seize compound in lieu of thread-locker, whenever torquing both the barrel nut and the buffer tube to the upper receiver as well as when torquing the flash hider to the barrel. In these instances, at least one and often times both thread surfaces (which are either/both aluminum or steel, depending) are black-anodized and thus quite "rough" in comparison to the machined thread surfaces found on automotive lug bolts/nuts. Granted, said firearms don't encounter the bending and/or shearing forces described in your video, however said weapons do experience high temperatures (e.g., the barrel nut-to-upper receiver connection easily reaches nearly 400 degrees F whenever firing long strings of sustained rapid semi-auto fire while the barrel-to-flash connection hider runs near 275 degrees F during the same firing sequences. In addition, vibration is quite severe. After firing tens of thousands of rounds under all manner of firing sequences and conditions, not a single anti-seize/torqued connection has come loose during firing and/or after cool down. However, whenever I want/need to subsequently remove/replace a barrel, etc., the connections can be easily unscrewed and then later on re-assembled, all without damage to the expensive parts involved. I've had to remove factory-installed/assembled screws (e.g., on my FN SCAR's) that had been either red/blue-LockTited and which required copious amounts of direct heat (I.e., propane torch flame) in order to soften the LockTite to where the connection could be unscrewed - when re-assembling, I cleaned/removed all the remaining LockTite and substituted Permatex anti-seize compound and re-torqued - all with great results. Similarly, using anti-seize in lieu of thread-locker on the small fine thread machine screws used to mount riflescopes - works quite well. Although the temperatures experienced during firing are lower at these points, the vibration is still quite severe and the torqued/anti-seize connections never loosen except when purposefully removed to change a scope, etc..

I own a Toyota and for decades now I always applied anti-seize and then applied 75 ft-lbs to the nut with the anti-seize on it. I'm now going to reduce the torque down to only 80% of the rated 75 ft-lbs, and torque the nuts up to only 60 ft-lbs just to make sure I don't over-tighten them. Thanks for this information.

Here's an idea. How about some chemical/petroleum/mechanical engineer type devise an anti-seize that does not lubricate so a lug nut can be torqued to its specified value to put the bolt in its design spring range. Seems like there should be something like that specifically for automotive use.

To all of you who are terrified of using any form of lubrication on lug nuts, whether it be oil, grease, or anti-seize, NASCAR has a dry film lubricant applied to the wheel studs on the race cars. Anything added to the threads/nut surfaces that alters the coefficient of friction is considered a lubricant. And, yes of course reduce the torque of lubricated lug nuts by 30%, but that number isn't as ultra critical as some would have you believe, due to safety margins. Dry torque specs will bring the tensile load to 75% of stud yield or 'Proof' load, so there is still a big safety margin to work with. The 30% reduction in torque on lubed threads still brings the stud to the same 75% of yield, so there's still the same safety margin to work with. Using the dry torque spec on lubed nuts will bring you right up to the limit of yield stress before damage is done, but i believe there's still an additional 10% safety margin built in to the max yield stress numbers.

@ASJC27

This is mostly true but lacking some important information that may lead people to the wrong conclusion. First, you are correct that torque specs for reusable fasteners are generally recommended to be calculated for around 75% of the proof strength (not yield strength - they are related but different). BTW the few wheel studs torque specs I looked at were more like 65-70%. However the crucial bit of information that is missing here is that even a perfect application of the torque spec is no guarantee that this will be the resulting preload. The 75% figure is only the average result. There is a huge variability in this. DOD document MIL-HDBK-60 states a variance of +-25% in preload for a given torque figure, while a test by Blake & Kurtz on 20 identical dry bolts torqued to the same figure resulted in variance of +25 -31% in preload. The bottom line is that a torque spec calculated for 75% proof strength may result in as high as 94% of the proof strength in some bolts. That 94% is not a coincidence. The 75% rule of thumb was chosen to guarantee that even the outlier bolts will not exceed their proof strength, so no bolt will acquire a permanent deformation, hence allowing reusability. The margin is therefore very low for some bolts, so if dry torque specs are used as is on lubricated bolts some may deform with all the implications of that. This huge variability is partly why using torque to achieve a given preload is avoided in critical fasteners, and instead more advanced methods are used, like a prescribed amount of rotation, DTI washers or bolts stretched a prescribed amount.

@pdvmotorsports

It's a shame the guy making decent technical content embraced your comment with a heart. This is terrible information no one should follow. @asjc27 pretty much nailed it in that 75% is the target but from testing the OEM knows what they ACTUALLY achieve AFTER relaxation of the joint with their $3,000 electric torque wrenches. Depending on the joint, OEMs design a torque or torque to angle (not yield) joint to 50% of proof load. This is usually the WORST case scenario (not better because you have 50% margin) which was partially covered by the video because you're way more likely to unload the joint which then puts 100% of the load in the bolt and you will have a failure. Once they're OK at 50% they may do some more testing or simulation at other pretension levels but if the joint looks good they're done and they target 75%. If they need to sharpen their pencil due to some issue they're seeing in testing or FEA they will pull out their bag of tricks which can include better tooling and controls on the assembly line to bring that +/-25% down to 15%. Your torque wrench will never replicate this and you should follow the unmodified OEM procedure if it states anything other than torque to XX ft-lbs. Also, throwing out a blanket 30% reduction if you lubricate is equally dangerous for many reasons. People have no idea how many things can vary your actual bolt pretension. The RPM at which you rotate your torque wrench up to the click/beep will change the pretension by a fair amount. Same goes for applying the torque to the bolt and holding the nut steady vs torqueing the nut.

I've been an ASE certified mechanic for 11 years worked on thousands of cars and owned many cars for hundreds of thousands of miles and yet the ONLY problem I've encountered is lugs without antiseize on them. Every time some crack head at a tire shop blasts your lugs off and or on, at full speed with a impact gun is what will get this problem started. I do what my instructors had tought me and it never fails, ever. Now over applying antiseize is bad and less is more when it comes to high load applications but in mine and every ASE certified master tech teacher I've ever learned from, has the derect instruction to use it after factory bolt coatings have been compromised. I'm interested in diffrent types of antiseize and measurable amounts in application alongside the effects of heat/cold and material grade that had antiseize applicated. Re-torque lugs you use antiseize on, is in my opinion strongly advised as over applying will allow spec to looses as where just enough will stay in spec. Remove excess if torque spec fell out after 50 miles, then again at 50 miles if there was a correction. [do it right the first time] Spark plugs on another note can react negatively with antiseize especially those with a low torque rating to begin with but otherwise high torque plugs, do just fine and prevents the use of adding a helicoil down the road. My experience is tried and true with time to tell and all I suggest is if you do use it, don't over do it. .5-1 milliliter appropriately placed will do its job correctly but do cover all the threads. Application is KEY! A shirt ton of the stuff is all bad and unfortunately in my opinion voids this experiment, I like the example though! To add some gravity, I placed 1st in Skills U.S.A., a national competition for mechanics.

@EmbraceMaking

7 жыл бұрын

Thanks for weighing in! I will agree with you that for re-torqueing there is a place for anti-seize. The thread surfaces get chewed up after the first torque application and then friction increases, thereby reducing preload on subsequent applications of torque. Some amount of anti-seize can "restore" the original friction properties and give you the initial preload. In my opinion, however, most people blasting lug nuts on and off are not 1st place ASE certified mechanics and they will definitely not measure out the amount of anti-seize being applied. Most people don't even recheck the torque on their lug nuts after 50 miles. So the problem becomes that people will over do it with the anti-seize and they over tighten on top of that (no torque wrench, no torque stick on an air gun, etc.) Professionals such as yourself take much greater care in what they do.

I agree. Less is always better when applying anti-seize but it is definitely necessary in certain - not all - instances. For example, did you know that NGK spark plugs have a proprietary anti-seize on the threads from the factory? However, once removed they have to have anti-seize added if you want to re-install them. Sparingly, of course.

Would be interesting to see what impact antisieze has on corroded lugs, I'm guessing it probably brings clamp load closer to "new' specifications. As a rule I antisieze all my lugs and use a torque wrench, never had an issue with stretched threads or broken studs.

There is a video on KZread where a guy does the same test with new, corroded and corroded and lubed bolts. Corrosion reduces clamping force to ~30% of clamping force of a new bolt. Lubing it brought it back to ~80%

Great video! This will come in handy at work. I run into this issue quite often. Been doing tires and suspensions over 20 yrs. I live in the Midwest and because of the weather, moisture, salting the roads in the winter oxidization and rust is guaranteed. This can make it a pain to remove wheels. It’s not uncommon for people to grease up their hubs, lug nuts and studs making it easier the next time you have to remove them. But I definitely don’t recommend it on studs or lug nuts. We actually have to remove it with brake cleaner when we come across it. It’s mandatory! Greasing the studs or the lug nuts and then torquing at factory specs can actually stretch the studs to the point where the nut threads no longer line up with the bolt threads. When this happens they’re a nightmare to get off and back on again. This also can cause a cross thread and the stud now has to be broken off and replaced. It’s caused by over torquing. Grease or anti-seize allows the bolt to turn well past its dry torque specification. By removing your wheels seasonally for a simple rotate or balance usually eliminates this issue anyway. The longer the wheels stay on the vehicle the more likely they wheel oxidize or rust on. So instead of greasing them up just remove them once in a while. Lol... It even says right on the box of anti-seize do not put on lug bolts or nuts. Wheel retention is extremely important. A little grease on the hub is fine but putting it on the studs or lug nuts can alter the clamping force. It’s definitely not recommended. Both the car manufacturer and TIA say a dry metal on metal torque is required. But if you insist on greasing them bad boys up I suggest under torquing them by 25 percent and re-torque them multiple times after driving to insure they haven’t loosened.

Thanks Gerald! Was this just from their generic anti seize product?

I’m dealing with a similar issue, but in a different application. I am pondering lubed vs unlubed torque value for keel bolts in a sailboat. So nice to see you replicate the approx 25-30% difference in clamping pressure that most bolt torque tables show for dry vs lube bolt torque values. I’m going to use about 25% less torque than my sailboat mfg suggested dry torque value and use anti seize. My reason for this is twofold: first the bolt/nut are stainless steel (which is prone to galling), and second, I want to get the clamping pressure values for all 12 bolts as close as possible. Again, thanks for posting this. Very helpful.

If you were to instead observe the load gauge to arrive at the desired bolt tension (e.g. 5.5K psi preload = 60% elongation or stretch), why should it make a difference as to how much torque was applied to the fastener? Would dirty dry threads result in more accurate fastener tightness? Creating the desired bolt tension or stretch is the objective, yes? What am I missing? As I mentioned, dry threads add rotation friction which must be overcome to apply the proper load to the assembly. A lubricated thread should reduce that dry friction variable and minimize the rotational friction to arrive at the correct bolt tension regardless of the torque needed for that to happen. This is the reason why measuring actual bolt stretch is a better method to arrive at the desired bolt stretch. However, not all threaded fasteners can be measured end-to-end. Lacking that capability, try torquing clean, lubed threads at 70-75% of the specified spec (~33 ft.lbs). That should get you in the same preload ballpark as a dry lug nut tightened at 44 ft. lbs. for 5.5K psi preload.

I use anti seize on all bolts and nuts, except on lug nuts. My honda manual does not mention it to put anything on lug nuts but in most of the other places, yes. Good video man

+dynaweave Engine grease would definitely provide a similar effect. It will reduce friction and result in more preload for the same torque. If the documentation for your vehicle doesn't specify, it would be safe to assume that it is a dry torque spec (for wheels). I've never personally seen a manufacturer specify lubrication/anti-seize for wheel studs.

Good info. However, it has to be remembered that friction changes as lug bolts corrode so that throws theoretical calculations off. I've known for 55 years (since my first car) that it is not recommended that lug bolts be lubed. However, I have lubed them for most of that time and I've never experienced a single problem nor has anyone else I know that lubricates them including professional mechanics. I do, however, generally torque them to slightly less ft/lbs.

Lots of people don't realize this though... or they are too liberal with the anti-seize / grease and they don't reduce torque... plus its hard to say how much. The engineers who designed the car also know that friction increases with corrosion and leads to reduced preload which is why they chose the torque value they did for the lug nuts in the first place. There is ample headroom on preload to account for reduced clamping force with corrosion. So even if you keep on using the recommended torque value you should be safe.

Conversely, would dry torque rating increase when blue/red thread locking liquid (that dries on threads) is used?

Interesting.....but you only did one bolt on each method. Is there any variance? Is the pre-load consistent each and ever time?

This video answered questions I didn't even know I had! Thanks!

To be honest I haven't put too much thought into it...so I'll think out loud here for a minute... loctite is not a friction modifier, so technically you shouldn't have any risk of over tightening your bolts. Second, loctite basically fills up the gaps inside of your threaded bolt/nut coupling and this is what prevents loosening. That being said, you may get the added benefit of preventing water(salt water) from seeping inside and acting as an electrolyte for galvanic corrosion to occur. I can't guarantee it will prevent it, so if it still does occur, you might be double screwed when you try to use a penetrating spray to loosen rust because the loctite will prevent it from getting in the threads. That's a tough call!

I think reducing torque specs by say 30% should be explored. At any rate has anyone had a lug nut problem that they contribute to using anti size?

I've been working on vehicles for over 45 years. I always applied anti-sieze to wheel lugs. I have never had a wheel come loose or fall off. I have never broken a wheel stud either. Lately, I have stopped using anti-sieze on wheel studs and now only use a light layer of wheel bearing grease.I still get the same results using grease over anti-sieze. I use anti-sieze on parts that are exposed to heat, such as exhaust manifolds and exhaust systems. Wheels studs do not get hot. Maybe a little warm, but not hot.

So just remove 30% right? Sounds easy enough My civic 2016 needs 80 ft/# (dry) so a simple conversion would mean 80- 30%= 56. So lubed would mean 56 ft/# of torque, right?

I have been coating lug bolts, studs, wire wheel splines, hubcentric wheel/hub contact points, and valve stem threads with anti-sieze for going on 50 years. Works perfectly. Never had a lug loosen or become significantly overtorqued. I live in the northeast where the powers that be just love to use dry and liquid salt on the roads, before, during, and after a snow storm. I use the never-sieze sparingly. A very light dry coat that colors the rust a silvery gray is more than sufficient. I have a background in the automotive repair business.

We need to have the torque requirement for the use of anti seize.

Whatever Ft-Lbs you are trying to torque to, just multiply it by 0.7 and you will get the Ft-Lbs you should actually set the torque wrench to. For example 44ft-lbs X 0.7 = 30.8ft-lbs Multiplying by 0.7 is the same exact thing as reducing by 30% Those of you in the rust belt and cold areas with salted roads can thank me later! It's extreamly easy formula to follow. My lugs are 80-120 Ft-Lbs according to Chrysler torque spec on my vehicle. I normally shoot for 100 Ft-Lbs and that means I dial in 70 Ft-Lbs if I use Nickel-Graph/Copper/Silver/Blend Anti-Seize.

Good tip. I suppose this wouldn't work if your nuts and bolts aren't already corroded. If they are rusty, putting anti-seize on them would probably even it out.

geat video .. at 76 years old I have always copa greased my wheel nuts / studs .. and almost never used a torque wrench .. never up to now had a wheel say bye bye.

You don't want antisieze or grease on 2-piece lugnuts like used on the super duty and heavy duty trucks with hub-pilot wheels. They are machined for minimal friction between the nut and washer, and for the washer to not turn against the wheel. Any lubricant on the washer face will allow it to spin against the wheel, which will gouge into aluminium wheels. But with stud-pilot or BUDD truck wheels, there is no such thing as too much antisieze.

Well done thank you very much.

The underside of the lug nut touching the cone seat of the wheel will most definitely affect the torque spec.

I live in Canada and we use a ton of salt on our roads in the winter and have not come across a completely seized lug nut yet. I change my wheels out for winter tires every year and by removing the lugs annually it seems to be enough to prevent them from seizing.

I am only wondering about this because the bolts on my Volkswagen can get very difficult to undo. I know that this is a problem with aluminum and similar wheels. I once had a '95 LeBaron with aluminum wheels and but I also had those horrible lug nuts with the thin cap on that car. The cap on those miserable things would eventually come loose and cause problems trying to get it off. I don't know if Chrysler still uses those awful lug nuts but they are sometimes hard enough to remove even when that metal cap on them does not get messed up. My Volkswagen does not have that problem because they did not put those stupid thin metal caps on them. Instead they left them a plain bolt head and there are plastic plugs that hide them. When lug nuts become stubborn like that the wrench that came with your car spare tire and jack will just make it seem practically impossible to remove the lug nuts. You will feel helpless if you didn't bring a breaker bar with the correct impact socket for your car.

Hi Charles, sometimes the problem is material compatibility. Certain material combinations will accelerate corrosion in wet/salty environments.

As good as this information is when putting on lug nuts in winter climates with road salt usage a dry torqued bolt will rust in place and end with broken studs. So you torque bolts approximately 10% less to keep from overloading the studs. Sometimes there is NO good answer and in a world where the majority of bolts are NOT torqued with a torque wrench it is anyone's guess as to the actual torque anyway.

This would explain why my vehicle owner manual says not to use anti seize on the spark plugs. As far as rusty lug nuts, to get them off I would use wd40 or pb blaster and then use the power of leverage with an extension on my breaker bar. If it's that tough to get off you probably have bigger issues that need to be dealt with.

Better that you remove the rust and torque dry and clean.

Hello from germany. If the threads are in good condition I mount them dry, if they are rusty I clean them with a wire brush and give them one or two drops of oil. But I know that lots of oldtimer and 4x4 guys are using copper grease on the wheel nuts/bolts, and never heard that someone had an issue with that. In my opinion it might be o.k. to use a very little bit (!) of copper grease and reduce the torque about lets say 10 nm.

It's a torque vs tension problem it's hard to determine the right to work with a rusted bolt or at lubricated Bolt torque specs are rated on dry Clean bolts what you're really looking for is the proper tension

@EmbraceMaking

7 жыл бұрын

Thanks for the comment! Anti-seize will change the friction as I mentioned in the video which will increase pre-load (bolt tension) for a given amount of torque. As you can see, it's not difficult to change it enough to exceed the yield strength of the material and cause total loss of elasticity in the bolt. That being said, it's very difficult to quantify how much anti-seize is considered "too much," OR if any amount at all is acceptable. That would be something that would have to be measured experimentally I would imagine. So unless your co-worker plans on doing the experiment and then applying anti-seize with a syringe, I would recommend that he doesn't use it on wheel studs unless the manufacturer recommends it (and can provide a wet torque rating). So to answer number one and two at the same time, any amount of anti-seize has the potential to cause the wheel nut to back off and fall off if torqued to the dry torque spec of the bolt (stud). It can stretch the bolt and you will have zero clamping force potentially. Let me know if that makes sense to you :) Thanks for watching!

From 60% to 90% yield rating is actually a 50% increase in load, it is an increase of 30% of total load rating.

Yes, someone else brought that up... I could have been more specific to say that it is a 30% increase in the load with respect to the yield. It would be 50% increase if I was referencing the previous load as you stated.

Wong yielding a bolt only decreases the thread pitch (making the bolt out of dimension) but does work harden the fastener you must approach the UTS of the bolt to metallurgically damage it. Under pre-load lead to fatigue not over-preloading.

How is clamping force different from preload, does not the preload created the clamping force?

@EmbraceMaking

Hi Daniel, thanks for watching! Yes the clamping force is generated by the preload, however, it can be different. For example, if you have multiple fasteners, your clamp load will be higher than each individual tension load in the bolt. Also, depending on external forces, a compression force acting on the joint may increase the clamp load and decrease your preload. Check out the link in the description for a more in depth explanation! Thanks!

Thanks Andrew, I would not recommend that. You are lubricated the clamping faces where the wheel touches the face of the rotor. The lug nuts clamp the wheel to the surface and that clamping force along with the coefficient of friction is what keeps the wheels in place. The spigot is the little round lip that protrudes through the center of your rotor and locates the wheel dead center on the hub. This is where I find most wheels seize. I usually apply a little anti-seize there, especially before the winter and this makes it easy to remove the wheels in the spring and will not affect the clamping.

Forget the anti seize, just use a bit of axel grease. Use a half inch drive ratchet, torque it up using 3 progressive steps with the final being a very solid push/pull, and youre good. Done thousands of lug nuts this way without problem. Every broken lug bolt ive seen, except two have been from trying to remove when seized dry. The other two cases were caused by loosened nuts that were dry. I suspect their undertorque caused by thread friction whereby the nuts mistakenly appeared torqued but the torque was fooled by the rust of the lug and nut threads since I once caught a friend falling into that trap.

Excellent information, thanks and your explanation/presentation could not have been better. As an FYI and like others who have commented, I have used anti-seize on lugs for years with no apparent long-term illeffects. I never used a torque wrench because I've done this enough times to know what 75lbs of foot-force feels like. I will say that I likely let up a bit because of the lubrication torque ease. My bigger worry is too much torque causing rotor warpage. As for becoming loose, that will usually become apparent with wheel wobble at high speeds (alignment-like need). Regardless of my experience, I learned a lot from your video that will make me conscious moving forward. Well done and thanks.

If you ever had a difficult time with a car that has aluminum wheels you will know what I mean. I keep a breaker bar and socket in the trunk of my car and even then the lug bolts seem too tight at times. I still have the wrench that came with the car but it is really somewhat undersized for what it was intended for. It is not just a problem with my car but many of them. It is feels like whoever chose to include that wrench never had to change a tire before. I only ever find myself taking the wheel off the car to inspect the brakes. I am glad it is rare that I ever have to take them off the car.

M12x1.5 nuts. Very tiny bit of silicone grease along each stud. 80% of manufacturer specified torque. Have no problem with nuts, even after drifting or 1000 mile highway trip. No rust on studs, in UK where rust is eating every car away.

The biggest mistake I see people make are not cleaning parts thoroughly, especially rusty brakes, and cranking things down, way to tight, not good for anything, especially rotors. The argument should be made that just as anti sieze can result in a bad torque reading, so can a rusty wheel stud/nut, as that will create a lesser tight bolt, and inconsistencies between boIts, I venture to say, in real life, rusty instalations account for more problems.

In this article from 2019: www.caasco.com/blog/Automotive/dont-let-the-wheels-come-off-how-to-prevent-wheel-separation it shows that in a four year period in the province of Ontario, Canada alone, there were 389 reported cases of wheels separating from light (passenger) vehicles and 29% resulted in a collision. That obviously doesn't account for all of the unreported ones as well. I know as a percentage of all of the vehicles on the road in the province it isn't a huge number, but it's still significant enough that someone (multiple people) have probably been killed or badly injured as a result.

I do think though, you are touching on a very specific technical point, nothing wrong with that. I would venture a guess that the problem with wheels coming off on Monday has more to do with how much they drank on Sunday, and a general problem with lazy, carelessness. Also wheels are not standard in the ways they are attached, too many variants and complex spacers, binding nuts, et cetera, that complicates things. I've always appreciated the simplicity of a black steel, fleet style wheel and the lug nuts that seat into the nice beveled holes, spun in place with a 4 way lug wrench. Probably covered with a dog dish hubcap. When you start fiddling with simplicity, problems arise.

Went back for the fix, same problem. Said it was within specs. Took it to Bagge and Sons. The first thing the mechanic says is all the bolts are loose! In the end they did a beautiful alignment, car tracks perfectly, wheel is straight. The Just Tires kid knowingly sent me down the road with control arms ready to pop, this is stuff that goes on. I've driven more than a million miles in LA, taxis, Limos, I have seen some crazy stuff, one time I did see a wheel coming in my direction, it was a bigass, like off the back of a Vette, 10 Fwy and Crenshaw, from the oncoming lane, that was scary, it was bouncing like a ball, thirty feet in the air, went by me 100 ft away, I never did hear a crash.

Anecdotally, I have never seen anyone's tire come off that I have put on or have seen put on. With hundreds of variations in tire size, bearing size, levels of lubrication including anti-sieze, and levels of rust. And in many applications up to and including racing conditions and towing conditions. All torqued by hand with a fourway and no torque wrench. If a tire comes off then anti-seize didn't cause it.

So, the stress on the bolt is actually greater than 71,000 and 106,000psi. In fact, the stress on the lubricated bolt is very close to its yield strength. One more reason to use given torque values on dry, clean threads.

@@EmbraceMaking Actually, you were right the first time. It's Larry who made the mistake. Yes, a 3/8" 16 has a minor diameter of 0.2938" (not quite 0.297) which gives a minor diameter area of 0.0678 in^2 (not quite 0.0693), but that is the wrong area to use for stress. The tensile area of a bolt is not the one corresponding to its minor diameter. Remember - the threads carry tension too - so the effective cross section (the tensile stress area) is in between the minor and major diameters. It can be calculated (you can easily find the equations) or read from a table. Looking at a table, the tensile stress area of a 3/8"-16 is 0.0775 in^2 - just as in the video.

i love antiseize. car makers should give a wet torque rating.

Hard to control how much you apply so if they gave you a wet rating it probably wouldn't mean much.

I really don't see the problem here? Just use LESS torque than before. Also, keep in mind that those torque recommendations cooked up by the auto mfgs. are primarily for ease of assembly rather than repair work. Even a DRY bolt/nut will require a DIFFERENT torque rating upon its re-use when repairing. The simple putting on a nut, and then taking it off will CHANGE the threads enough to show a different torque requirement.

Many thanks! I lubed them 2 days ago!

So people its your choice what you want to do after watching video n reading comments, it seems both are OK as long as you know how to use antiseeze n how much to tighten-20-30% less people are saying, but what if some one else tighten lug nuts n not you n might use more? Both have ups n downs Also i am going to get a torque wrench, didnt know i should use one on lug nuts until recently

Hi Michael, yes, if you know what you're doing its probably okay, but that was the point I was trying to make. Most people don't reduce the torque when using anti-seize so that is why manufacturers recommend dry assembly.

Not sure if this is correct. I was told a long time ago when using anti seize go 75 percent of torque rating.

Someone said do 30% less

The manufacturer of some of the finest auto fasteners, ARP, recommends lubricating the threads as well as nut surfaces, and to adjust torque specs 30% less. Doing the math will confirm this reduced torque on lubricated fasteners will give the same tensile clamping force.
