Ok, I know that Opel wheel studs are 12mm X 1.5 pitch, but, does anyone know, off-hand, what the knurled area diameter is? I can get my own measurement when I get home tonight, but, I was just wondering, as I'm sitting surfin' the 'net.

They are 14 mm to outside of serrations x 10 mm in lenght. Back is 20 mm x 4 mm thick. Total length is 41 mm. That is measuring an NOS one.
