For those that use torque wrenches on their terminations, do you ever question them?
no, i question the quality of the chinese ungraded nuts and bolts.
now, when i am bolting up stuff where i can thru bolt it, and don't have to
depend on OEM stuff, i substitute 3/8-24 grade 8 allen head cap screws,
grade 8 flat washers on the cap screw side, grade 8 belville washers on the
nut side, and grade 8 nylock nuts. all american made. i am not a china hater,
but i've seen they seem to have a constitutional inability to produce a SAE
compliant thread.
3/8-24" grade 8 has the same torque value and compressive strength that 1/2" hardware
possesses, assuming the 1/2" hardware is grade 2 compliant. a lot of it isn't.
torque them to 35 ft. lbs. lubed, and be done with it.
for setscrew lugs, i don't use them, i hipress. if i have to use them, as on a breaker,
i use antisieze, and torque to specified torque, unless i see metal deformity, then
i stop.
