PINCHED NUTS QUESTION

OK, Just saying, There are lots of ways to keep a nut from backing off. The OEM engineers looked at everything available and decided what was going to work, ON THE ASSEMBLY LINE. Plus what would work for 10 years.
That is not where we are. We are reworking and reusing OEM hardware. Today the quality of OEM hardware has went to crap, softer "torque to yield" hardware and we get OEM head bolts that we shouldn't reuse. That isn't what these classics were made of. as for the above posts.... I did consider a center punch versus a chisel. Chisel is one hit; center punch is two or three.
I have the machinist handbook. I've studied Interference threads because I had to create them at my job as machinist. I know about the problems Chrysler had with the 3 bolts mounting the steering box in early models and all they went through to solve it.
And I know a little bit about the aircraft thing. I'll stop right there. Good luck to all.
