Z06 Lug Nuts??

I picked up a pair of 2001 C5, Z06 alloy wheels (OEM). Can someone tell me the spec for the lug nut....type of seat (acorn, bulge, etc). I know the size is 12mmX1.5.... Did a lot of searching but coming up empty. I may go either OEM or aftermarket....thanks.

The seat is 60 degree. The oem lug nuts are acorn. You can find GORILLA chrome (or black) lug nuts/locking lug nuts through some of the site supporting vendors (C.C.A. or HOUSE OF WHEELS, possibly?).
DISCOUNT TIRE also sells them in a box of 20. The chrome looks exceptional and they're all steel.
If you want new oem type lug nuts, try Gene at GMPARTSHOUSE, another site supporting vendor.
If you want used Z16 type lug nuts (polished finish), I have a complete set I took off my Z16 in favor of the GORILLA lugs/locks. I'd say they're a 6 on a scale of 1-10 with very minor corrosion on some of them.

Some places may also refer to the acorn as a cone seat

Hi 54fighting -

The 01 Z06 had a hollow lug nut with a screw on plastic cap.

In early 2002 GM went to a chrome clad lug, eliminating the plastic caps.

The did this because the plastic caps were prone to coming off.

I have Gorilla lugs on both cars now - and put the stock lug nuts and caps away.

I ordered mine here from Cajundude at www.gulfcoastperformance.com -

I recommend him as a good source at a good price - and he is a supporting tuner.

best regards -

The stock lug nuts on the 02 and newer cars are the same ones GM used on other cars going back to the mid 80s. They have a thin stainless cap crimped over an odd size lug nut. The cap tends to warp when the lug nuts are removed or installed whether or not you use hand tools. After several removals the cap can come off and leave you with a non-standard lug (neither english or metric) holding the wheel on. This isn't a nice position to be in and requires that you or somebody pound a sacrifical socket onto the lug with a hammer so you can remove it. Whatever you do avoid these types of caps whether they are OEM or aftermarket as they are crap.

I switched to McGard Chrome lugnuts. They can take repeated loosening tightening and no chipping.

Have had mine for 2 years and still look brand new.

Pep Boys has them - a little pricey but worth it.
