1/4 drive for lug nuts

No, they are different sizes...

Go to Autozone. They should have black in the size you need and will be around $22 for all.

0.002 inches different if they are both perfect, they aren't.

Yes they are very very close. and most lug nuts get slightly rounded anyway.

However, if you have a new 19mm nut without cap, and a 3/4 socket is put on that nut, the socket will wiggle.

I think a 3/4 socket will round new lug nuts over time especilly the C5 and C6 lug nuts with the aluminim beauty caps on.

Also use a 6 sided socket not a 12 sided socket for snug fit.

I use ARP studs and ARP lug nuts with an impect wrentch as my wheels are on and off all the time.

Did you find them in black? If so where, I'd like to order some as well.

I tried Autozone and they said they couldn't get them. I found some at a local tire/wheel place for $20 but they are painted. Guess I'll try them once.

Do you know Chris Crain that works at USASOC? He ussed to have a Grand Sport. I have spent much time in Hope Mills myself, especially in Rockfish creek.

I found some at a local store, see above. Discount Tire Center. They may have one in your area. Also driverfx.com has the good ones, McGuard, black chrome, for around $55 for a set of 20. If I don't like the ones that come in to the other place I will order from there.

Coincidence... I ordered a set of these Lug Nut Impact Sockets just yesterday. A better deal and colors too:

http://www.harborfreight.com/cpi/cta...unction=Search

Oops that link doesn't look all there... try adding item # 40035 to the search.

Curious, are you happy with these? I just got the same Harbor Freight set and the contact point between the nut and socket is not lined at all. The lining is external with just an insert. I need 13/16 for my lugs, but would prefer a set of truly lined lug sockets.
