Most domestic ars are running 7/16-20, 1/2-20 or 12 MM x 1.25 and grade eight material. Max torque is based on the size of the stud in use. Alloy wheels are more critcal for torque values than the steel wheels and discs moreso than drums. Your car..your call as to what method you use..the commercial industry is slowly learning that liability is incurred when bolting your wheels back on and on any chassis component removed, installed or adjusted during alignment...Our old cars are 1/2-20 nuts and threaded bolts..
The quality of material in respect to the lug nuts, studs and or bolts have not been lessened in my opinion.
