What's the correct torque for steel lug nuts and open end steel nuts for an H&R wheel spacer?

I've always used 105 ftlbs, with factory never seize on threads.

That is seriously tight ....................... (I know the "book" figure is high ................ I go much lower on a rally car and have never had a problem................ better if don't say what .................)

It corresponds to the correct torque of an 8.8 grade M14x1.5 thread, although is on the high side for being lubricated (anti-seize).

My best guess is that the nuts I have are either 8.8 or 10.9 (or something in-between), as the studs are 10.9.

Someone asked, I answered.

I've been tightening steel lug nuts, on Porsches, for over 50 years...to the exact same specification (which is the specification for early 911's with steel lug nuts.)

BTW....The correct torque for the alloy lug nuts is 95 ftlbs (130nm), with anti-seize.

^^ That is what I've always told tire shops to tighten them to and then I watch them do it with a torque wrench so they don't hit them with a impact...

I would assume the steel would be tighter as I thought the lugs themselves were "shorter" and had fewer threads contacting the stud.

The factory stuff is Optimol-HT right?
