Thank you

P1,



20 threads per inch sounds right.

I purchased a replacement set of lug nuts that are stamped 1/2-20 and they began binding and stripping (found bits of thread in the anti-seize). They got worse with time, so I put back on those that came with the rims (from ProComp). The ProComp lug nuts fit just as do the stock.



I'm not sure because I haven't measured them yet, but the lug studs may be metric and off just enough to cause binding.



Food for thought.

I don't think they are metric...the lugnuts from my Ranger (same as ST) fit fine on my '66 Ranchero, which has no metric anything on it. I've got a thread count gauge in the shop and could measure the thread count, but not the pitch or size.
