I as a carpenter worked with an old timer "millwright" that needed an extra set of hands just a touch more skilled than a laborer this one time. I work in semiconductor clean space construction and he insisted that we didn't need the fancy $250 an ounce lubricant on the threads what for saving money that's not his to save. Well the long story involved the steal equipment pedestal, core drill bits, a mag drill, taps, some red hot swearing and some smuggled in dawn dish soap that we use as lubricant whenever we need to cut stainless. And by "we" I mean "me" because at that point in my career I was still an apprentice and knew far more than the guy with the millwright book. It's amazing how many individuals of a skilled profession know less than the indentured tool carriers that are loaned to them from other trades.

Core Memory Activated: Back in my days as a nuclear plant operator in the US navy we had stainless infrequently operated primary coolant valves that had caps that fit over the entire bonnet assembly that were sealed with a self-presurizing metal o-ring. The valve caps themselves had acme threads to reduce the chance of galling, but every time the cap was removed we had to clean the threads and apply colloidal graphite (neo-lube) to both threaded surfaces and we had a special procedure for re-installation of the cap that basically said the cap must be spun on no faster than 30RPM until the surfaces mated the O-ring and then when torquing, 5 seconds per flat and 5 seconds between flats. We never had a galling incident but did have a scare when the brass insert that had the stem operating threads fail and the valve couldn't be shut. Thankfully it was part of a double valve isolation and the other valve was working properly.

We actually stopped using stainless steel bolts at our aquatic center. We switched to galvanized bolts because we were finding that the chlorine in the air and water were corroding the stainless bolts from the inside. We would find a stainless bolt with the head missing and the inside would be corroded away. Maybe it was the wrong grade of stainless. The galvanized seem to hold up better for our use and are much more apparent when bad

Stainless is only stainless when it has oxygen around it. Inside of a bolted connection with water (and especially chlorine/salt) in an anaerobic environment it will happily corrode away. This is a big problem on sailboats with stainless bolts penetrating a cored fiberglass surface. If the core material (often plywood or end-grain balsa) isn't sealed properly at the hole, water will get down in there and create a perfect environment for corrosion. The visible parts of the bolt will be shiny and lovely, but the part doing the work that you can't see is corroded away to nothing. Silicon bronze is a much better choice as it doesn't have this problem.

When removing exhaust flange bolts, i've found it's far easier and faster to use righty-breaky vs.. lefty-loosy to just snap the bolt and replace than pretend it will come loose; what happens if you try to CCW the nut, it will loosen just enough to spin the whole assembly and you'll never get a strong enough grip on the other side.

The Galling problem is especially bad if the SS bolts and nuts are put on fast, as with a battery operated tool. My brother used to use SS bolts and SS nylon lock nuts and he had a failure rate of 10 - 20% where the bolt would seize, and you'd have to snap it off to remove it. Nickle never seize helped, but was not a cure. The only thing that really worked was to only use hand tools and put the bolt or nut on slowly. Interestingly, this type of condition, known as Galling, Friction welding, Cold welding happens in milliseconds and once galled, the fasteners can only be removed by cutting or snapping them off using great force with wrenches or ratchets. It only occurs, to my knowledge with SS, Titanium and Aluminum.

So for the military usage we supplied, the approved procedure is to use different alloys of stainless in the nut and bolt, they must both be passivated, and they get never-seize appropriate for the environment. Different alloys are less likely to self-weld to each other, the passivation layer prevents bare metal on metal contact, and the base of the never-seize (zinc or copper) provides a further layer of separation as well as a galvonic barrier.

As I understand it almost all stainless fasteners used to be lightly coated in parifin prior to shipping to prevent galling. Now it’s seldom applied. I learned the expensive way antisieze is not a lubricant. Ruined a $400 ring less piston on a 5000psi compressor.

I seem to remember that using dissimilar stainless grades for bolt and nut used to be a cure of sorts for the problem. ...assuming that both grades were suitable for the job in hand of course.

We used a lot of stainless fasteners on ground equipment at corrosive coastal locations. After a while when needing to take something apart we didn't even waste time bringing wrenches, we brought a cutting torch.

Be more worried that they're loose. When loose, you no longer have solely shear force on the bolt, which itself is highly damped by the friction between the bolted components.

Ya I know its abouts shitty stainless. Grinder or bigger bar works for me and lots stainless antiseize

18-8 or 304 Stainless and only tighten with hand tools, never used anti-seize on any hardware and never had a fastener seize up on me, I think it really comes down to heat during tightening (the hotter the bolt, the softer it gets and bam you have galling), this usually happens when tightened too fast, like if cross-threaded or with power tools! Aluminum tapped holes with SS fasteners into them can be quite tricky though, for that we helicoil the Aluminum first then we put the SS fastener in, prevents the two from galling together. Plus the Aluminum we use is Iridite coated, this also helps to prevent galling for holes that cannot be fitted with a helicoil. I mostly just work with SS fasteners from #0-80 up to 1/4-20 though, granted we use alot of them, for some of the radio systems we do, we usually have upwards of 100-200 screws per unit (lot's of tiny screws spaced very close together to prevent RF leakage), most of what we do is custom so it's all assembled by hand with a tiny hex screwdriver.

Yup. This is likely the result of someone pounding them on with a power tool. I haven't worked a lot with SS hardware but I've galled enough of them to know that when there's risk you go slow, and you can always get the job done well without galling issues if you don't force the timeline.

For our water treatment plant pipework, we use 316l bolts with a generous amount of spray on aluminium lubricant. But anytime we're bolting mild steel stuff, we go with galvanised, it just galls up really bad otherwise

Such a great work 👍👍

Stainless steel has small burrs that heat up during tighting which is referred to as galling. Even going slow will seize the nut to the bolt before it gets tight. Little antiseize works perfect to avoid this.

@Jmoneysmoothboy

9 ай бұрын

"Small burrs" heating up during tight-en-ing tightening is NOT referred to as galling. If it were "small burrs" then it would not be an issue because they would just snap off. The problem is that the surfaces are incredibly smooth and mate with close to 0 clearance and then torque is applied which gives negative clearance and just like in anime the surfaces realize they are one and cease to be separate.

@Hydrazine1000

There is no heat involved. This is why "galling" is also often referred to as "cold welding". In direct metal-to-metal unlubricated sliding contact the thin surface oxide layers will break and the contact pressure will fuse the mating surfaces together. Fun story: the first cameras taken into space came back seized. Hard vacuum means that after sliding no protective new oxide layer would form on the stainless internals, so galling was the result. Hasselblad, the well known camera maker, had to gold plate the camera internals to prevent this from happening again.

Love & respect from your long lost brother

1.4401 or similar chrome+nickel+moly steel for stainless aquatic/marine applications, same goes for welds, those tend to self-disassemble if you use 1.4301 (18/10) or other cheaper stuff even if it's just your filler/electrode/wire. And stay away from any aluminium inserts and rivets, those act like artificial cathodes if used below the waterline and crumble faster than it took you to install them.

Thats not skookem

Well crap! It took be a few views and reading the comments to clearly understand what/when the bolts were seizing but when I got it was just as you were saying… I was like “well crap! That is what happened!” I had two brand new SS nuts n SS nylon lock nuts… I believe I drove them on with an impact drill… they locked up just as you and comment said and you showed! I had assumed I had two very expensive defective nuts and it was the nylon lock that was too small and defective! I paid the price and had to use the Mildred tool Roto cutter disk to cut them off… second time I hand tooled them on. Thanks for the edumacation! :)

Might have to look into that when I stalling expansion bolts for climbing. I have had a few seize up on me.

I've used stainless bolts 316 and 304 for a decade on Harleys, never ever had a sieze. I use blue Loctite 243 on every thread, tighten them snug by hand then torque a bit less than the standard torque for that bolt size. Nothing ever comes loose, nothing ever siezes, nothing ever breaks. 👍

Learned this lesson over the summer building a boat dock at the beach. Spent a small fortune on 316 hardware. My question is how long will the 316 last bolted to aluminum bracing? I did have the aluminum structurally anodized. But I'm guessing it's only a matter of time before corrosion begins at the contact points. The structure is all FRP so no worries there.

316 will be fine, the aluminium will not. You need to use the right material to prevent corrosion, and thus inconel bolts in aluminium, and also a thread sealer to keep water away. 316 will however slowly corrode in salt water.

I've had to snap a number of galled stainless bolts off - 1/4" you can snap off. The 3/8" U bolt on the other hand.... The trick is to use a black oxide coated stainless nut, or a regular steel nut. The dissimilar metals at the contact surface makes all the difference.

We used them a lot putting buss work together in substations. They sometimes would gall just finger tightening them. Then had to use a breaker bar to snap them off

Looks like the bolt holes no longer line up also. It is probably for the best that all your impact drivers are back home, in bits, on the healing bench.

To add to your enjoyment, start looking at cable clamps. You won't believe how many you'll find that have been installed incorrectly. Seems many people are unaware of how to saddle a horse. Apparently, no one inspected this installation.

My helper at work installed a 1/2 inch stainless bolt with a ratchet. He said it wouldn't torque down. I told him to remove it. He started with the same ratchet. No go. 24" breaker bar... nope. I said get the Snap On battery powered impact. Over 1000 lbs of torque and that thing just smiled at us. Ended up cutting it with a die grinder. Anti seize ALL stainless hardware, every time.

Before spacecraft hardware is brought into a cleanroom, it is precision cleaned to remove all surface contaminants and oils (these can later outgas in space and contaminate other pieces of hardware). I was once told an amusing story about this: an engineer was working on a test unit prototype and refused to wear gloves, stating that it wasn't flight hardware and the skin oils wouldn't matter. He developed the assembly procedure under this setting. Later in the mission, it came time for the *flight* hardware to be assembled; every single fastener on the system galled and stuck like crazy. The oils of the engineers skin had worked as an anti-sieze compound, preventing galling; when the flight hardware (which had been cleaned to spotlessness) was assembled, the metal immediately cold welded. I experienced this firsthand myself, when assembling a nitrous oxide feed system for an experimental rocket motor. I had plenty of experience with working with black steel pipe, and never had an issue with galling (as typically there was leftover cutting fluid from when I cut the threads.) We had just bought hundreds of dollars in stainless steel fittings for oxidizer compatibility, and meticulously cleaned them of any oils and greases. Imagine my surprise when, after threading everything together, I discovered that pretty much every single fitting had galled and destroyed threads.
