Overtorquing bolts also distorts and stretches the threads ..... whether in automotive , industrial , or aviation.
Do a little test on your next coffee break in the shop ..... and do it in front of all the musclemen who figure tight as hell is good enough.
Use common grade hardware store bolt , 3/8" by 2" long. ...... place a nice stack of washers on the bolt until there are only enough threads showing for the nut to be installed ...... use two wrenches and tighten normally ..... then as hard as you can .... tighten it a lot more.
Spin the nut off , remove the washers , and try to spin the nut all the way down the threaded area .... you will only get partway because the threads have been stretched and the nut will bind. You should even be able to visually see where the threaded area has stretched.
Next time you are having trouble changing the tire on your car because the wheel nuts are hard to turn ..... some muscleman at some gas station has stretched the wheel studs with a 250# impact wrench.
