Pep Boys, lol! I've been a ARP customer for 20yrs.. Rod bolts, main studs, rocker studs, and have their lug studs in my Renegade right now.. Moser and Strange make lugstuds of the same caliber, the best... Only about $12 per wheel, great investment! I have seen some primo parts packaged with counterfeit fasteners tho, thats why I said be carefull.. Sometimes the manufacturers don't even know that their fasteners are bogus.. Just that they are the best price, and keep the overhead down.. After all, they have the right markings.. You or I cant tell either! Keep a sharp eye! Those wheel spacers are nothing to dink around with, but your no youngster, I'm sure you know that.. Counterfeit bolts, LOL, sounds silly huh? Be carefull, because they ARE out there!
Yes I looked at the engineering materials charts again, just to make sure of my own memory.. "grade 8" is medium carbon alloy steel, quenched and tempered, 150,000lb max tensile. 120,000lb yield, 120,000 test(zero deformation).. "AISI 321 grade B8T" is Nickel Chrome Stainless instead of carbon steel, 100.000lb max tensile, 100,000lb yield, and the charts dont give a zero deformation test rating... Interesting stuff, both are tuff enuff, but the stainless doesn't seem to have the same give before it snaps..
Checked 4 diff charts for sources.. Just wanted to make sure the #s are consistant..
No insult is intended wide, just being the sage word of caution from experience
