I'm a mechanical engineer working in the defense industry. I do a lot of calculation work on fasteners used in critical applications. As a result, I'm a total torque spec nerd when working on my own cars. You guys nailed a lot of the science. Only thing missing was mention of thread shear during the overview of failure modes, but maybe that's too much. Seeing the 'Donut take' on something I do professionally was awesome!

I work for a fasteners company, and those types of studs are no joke. They are used in the oil and mining industry, and man, just reading through their spec sheets is insane.

I do structural testing of aerospace hardware. We had a steel test structure that had some 2" high strength bolts intended to be torqued close to yield. During install we broke one. Turns out the bolt coating and lube we were using had a much lower K factor than what was thought. So our torque resulted in more tension than we thought and overloaded the bolts. Fun fact: some of the bolts on RS25 rocket engine are tightened with the use of an extensionometer to precisely measure the exact stretch created in the fastener.

As a senior Mechanical Engineering student, I gotta say I really appreciate this. This was really well done.

EVERYTHING that touched the floor was to be thrown away. Bolts, clips, and even finished goods. They didn't want dust anywhere near those parts until they were fully assembled to the vehicle.

Watching this I knew that socket was going to give long before that 1" bolt did. Glad no one was hurt and this was a great explanation even for someone who had a pretty good idea what was going on anyway.

Did something like this once me and my dad impacted the bolt then manually with a breaker heated with rose bud until after all that then we realized it is a brush hog and was tightening smart I know

I could really have used him right now

I was rebuilding an engine many years ago and accidently used the torque spec for fastener listed below the fastener I was working on. I was supposed to torque my rod bolts to 10-pounds but wound up torqueing them to 100-pounds. I torqued several this way and didn't realize the error until the threads ripped out of one of the bolts as I was tightening it. Thankfully, a new set of rod bolts was not that expensive, and my local engine shop was able to get them the next day.

As an Aviation Technician this warms my heart to see. I watched a video before changing the control arms on my Sunfire. The guy in the video said "just tighten it as hard as you can. You don't want this to come loose." I corrected him in the comment section and got blasted by people for it 😄.

Later : Donut is where i finally got my physics scores an A+

Day 67 of asking for the team to design a Dirty Dirk's Blinker Drink T-shirt from the Wheelhouse: Car Terms Every Car Nerd Needs To Know

A cool thing about bolts/pins is some are meant to be crushed. I work with pins with threads on each end with opposite rotation from one another and by torquing the nuts you squeeze the center, expanding a Teflon piece in the center to make sure it doesn’t move in case a bit falls off. That being said we also step up the torque to keep it centered

I love this video! I work in the R&D lab of a fastener company, and this is precisely accurate :D

Can someone explain to me why he left the sticker on the face shield the entire time?

We used bolt stretch on main journal bearing studs using a hydraulic wrench as this gave more reliable torque results than using a standard torque wrench, specifically because of the size of these studs( these were used in a 5,000 hp genset) we used a dial indicator and they had to stretch to specific length, these were .032. If they didn't stretch after going up to 10,000 psi, the bolt had seen plastic deformation before( either by use or an imperfection in the forging process) and was thrown out.

I was wondering about this for a while. But at the end the explanation was correct.

I still want to see the thing break...i thought y'all we're going to pull it off, but perhaps it's a job for HPC 👀

Him: "And it didn't fail, so what gives?" Me: Obviously not that bolt....I'll see myself out.

3:30 after the material experiences plastic deformation, it will still have some elastic deformation that will reverse or 'snap back' when the load is released but your stress/strain curve will be shifted by the amount of the plastic deformation.
