Lug Nuts

[camaroman1969]

Hello everyone!!!  Would anyone know if the lug nuts on Camaros are suppose to be "plated" or just be a "raw lug"  The reason I ask is, because I bought a real set that have the three (3) diamond symbols stamped on them.  It looks like he wired brushed them, but I don't want them to rust.  Any info will be helpful.  Thanks guys!!    Don

Hi Don,

As I understand it, GM used a few contractors to make the nuts so the face marking could vary. I know you asked for a '69 but I did check my '67' which have the original nuts, and found the following:
67 04B LOS - waffle pattern on face - remains of zinc plating on all nuts
67 05B NOR - DMC stamped on the face - zinc plating on all nuts

I would think zinc would be used for a fastener like this.

GM used 500,000 lug nuts every single day, from many different suppliers, and each supplier had to have his identification on the face of the nut, which was either zinc plated or zinc chromated - there was no such thing as a "raw" (unplated) lug nut. See the GM lug nut drawing below with notes on supplier identification and plating choices.

John Z and Mike,  Thank you very much for the info on the lug nuts.  I had to ask, because I wasn't quite sure.  These will be headed for the "plater" now.    Don

Did this document start 9/30/1929? Is that what it reads lower RH side?....Joe

Yup! 1929. Looks like it had 24 revisions after that.
