Base OEM Lug Nut Size

[09cs]

I'm wanting to get my dad a set of new lug nut sockets for Christmas, and want to be sure it includes the correct size for his new Shelby. Are they the same as the 350/R, 21mm?

Thanks!

Oh 9: Yes, my factory lugs were 21mm.

13/16" is a better fit if your nuts are new and you intend on keeping them as fresh as possible (assuming its the same nut as the GT's)

Hmmm...WD, I didn't know that but I just checked again and you are, as usual, absolutely correct. Dang Ford...I thought everything was Metric now and the 21 seemed to fit just fine. Duh. I only used a "safe" 21 socket on mine and only once when I switched to Terrance's Ti versions so the originals are not marred at all. Why I'm keeping them, I'm not sure but maybe the next owner will appreciate my hoarding.

I do prefer metric but my brain-eye calibration is still SAE.

Thanks,

To be honest I think 21mm would be fine for 'careful' use - rather than banging the shit out of them with a worn socket rattling around on the end of an impact gun

I do wonder if that's (partly) where these nuts got a bad rep from in the first place ... ?

I found a nice 13/16 wheel socket surprisingly hard to obtain in the UK, I bought (and returned) two sets of wheel sockets that advertised as having 13/16 in them only to find that in reality the sales info was outdated and the socket was substituted with a 21mm.

Then after finally getting one, I then decided to swap my nuts out for McGards and they use 22mm which isn't in my set that has the 13/16 ... I really do have a skill for turning a simple task to shit ...

Oh man, that was funny, WD!

But time to get back to work, I'd like to get her sitting on her own shoes today.
