what size lug nuts on an 84 c10?

[benoit454]

What size studs/lug nuts would be on an 84 c10?

1/2?
7/16?
12mm? 13, 14, or 15mm?

I know my 85 monte carlo uses 12x1.5's and so did my 86 camaro. Not sure about the 84 c10 we just got though.



Reason I ask is later on we hope to get some crager s/s wheels for it, and I know they have 5x5 bolt pattern right? The descriptions say some will not fit 14mm applications. So it made me wonder if they'd be metric or standard. I know it's a dumb question because you could remove a lug nut and see if it or the stud was marked, but I figured some of you guys would already know the answer.

TIA for the help,

Chris.

NICE!!!

Thanks alot guys. I have a brand new set of chrome lug nuts that are 1/2 x20's and I can use them on it for now. I just needed to know for sure before I pick out what wheels we want to put on it.
