So how do wheel stud sizes work? From what I've found a stock wheel stud is 12mmx1.5 and 2" long. Is that the same as a 1/2x20x2 stud? What about knurl diameter, knurl length and underhead length? I was looking through Summit Racing's selection, a bunch of the wheel studs they have list a bunch of these measurements. What are the stock studs?

our stock knurl diameter is .509 and it is a 12 mm with a 1.5 thread pitch and the stock length is 1.5 inch

Cool, thanks. Is 12mm x 1.5 the same as a 1/2" x 20 stud?

1/2 x 20 stud is a little bigger in diameter. a little over a 1/2 a millimeter larger in diameter
