Does anyone happen to know what the thread at the back of a Grp4 front wheel stud is please?
Where it goes through the alloy hub and you put the nut on the back of it.
Ive tried and tried tried to identify it but failed miserable at every point. The only thing I
am pretty sure about is that it's Imperial but thats about it...
I thought it was 5/8 UNF but a 5/8 UNF nut is no good...
Cheers
Rob...
