>>18130045Nah listen I worked for GM, VW and for 10 years sold bolt testing machines to people who make bolts and Ford and Boeing from my own company. I sold tools into carplants for that exact operation. Sometimes you see that in a bolted joint with dissimilar metals like A/C systems with a steel nut on aluminum, but in this case, it was cross threaded and the lazy mechanic did not bother to make sure it was threaded in before he took an impact wrench to "drive it home" which it did half way down the stud until the impact wrench ran out of momentum. It's not torque that holds the wheel on, it's tension and I could write a book on this but look at the undamaged part of the bolt. That thing never had a chance. I bet it was hot for an hour when it got backed out. Imagine the noise that was happening and not noticing the bolt was turning with great difficulty. Fuck. run the bolt in, snug them up in a star pattern, then 1/4 turn. Is that enough? Yes because the shear load on 5 under torqued steel bolts that are a little snug is way higher than the strength of a thin wheel's rim. You hit a "Detroit Size" pothole and the wheel dies first. That taper makes it almost impossible to snap under the head, and that is where a shear failure happens because of cold forging the head. That's why there is five or six or eight bolts. If tightened to 90% of the yield point like at the factory, only 3 or four would do the job. The extras are to idiot proof the wheel.
