not sure if this helps, best i can do
i have stock lug nut side by side with sahara (jk) lug nut
they both fit thread, our (wk2) stock lugs look a little bit longer than the sahara. thead is the same they both turn same.
so if sahara is 12mm then ours is definitely the 14mm
The wk2 requires a 22mm socket, or at least that's what I use.
I need to order some aftermarket black lugs for the Jeep and I don't know how to find the size I need. I haven't been able to find a straight answer. I know that 12mm x 1.5 is not the right size as that is what I ordered and they didn't fit Looking for some help on which ones will fit (in black of course).
