Dorman lugs, in longer lengths are available from SummitRacing, if you need them. Most newer wheels need 60 degree lug face.

It sounds like you're just buying lug nuts but if you need studs the knurl size is a factor.
I've got a few Dormans I use where the knurl is a touch bigger and they pull through hard but that's better than loose. Turning the lug nut and having the stud turn with it is a horrible sinking feeling.
I've had a few Corvairs with aluminum wheels show up here with stock studs and like 6 turns of thread retention. Gives me the heebie jeebies as they just may fail at the worst possible time.
Stock lug nuts on wheels made for 1/2" studs are just as bad as they can pull through the wheel.
Proper hardware can add quite a bit to a good deal on wheels.
I hate uni-lugs.

Jim- are you referring to the .475 knurl ones for the Corvette? Do you know of any available that are longer than the 1-3/4 ones from Dorman? I've got some alloy wheels on order and it seems like the Vette ones will barely be long enough but I can't find anything longer that won't require boring out my hubs.

I have Dorman studs out in the garage and computer in the house upstairs after I take my shoes off. I'll try to remember to look into what I have.
Way back I looked in the Dorman catalog which lists all the pertinent information.
