Thread: B13 wheel stud knurl diameter / size / dimension

What is the diameter of the B13 wheel stud knurl? I know it's something close to 0.565" or 0.568" but I'd like to know the exact measurement. Maybe it's in metric? I tried searching this and the old forum with no luck.

I'm thinking 14.3mm is the right dimension from looking at these offerings:

I can speculate all I want. I'd like a real answer please.

I'm thinking 14.3mm is right on the money. This is equal to 0.5629921259842521" or 0.563".

It is the size for the front S14 wheel studs, and I'm pretty confident ours are the same.

Apparently up to 0.570" is acceptable.

Here's some info on the NISMO wheel studs for the B13



I'd agree on the 14.3 as well.

Doug, that's what I was looking for. Dimension "C" is also of great use to me. Thank you very much.

I'll just leave these here.

Any chance someone knows how to get the wheel stud dimensions for a B15?

If they use the same NISMO "upgrade" (AKA downgrade) then we know that size. I don't see why Nissan would change it, but they've done crazier things (S14s have different wheel stud sizes front-to-rear ).
