did you not see this post in the link to the thread Texas82GP posted..?

12.73mm Knurl.(.501") is stock. Stock length is 41.5 (1.63") (Dorman 610254)

For 1/2" longer studs, you can use Dorman 61323 which is 54mm lont (2.12") and has a 12.8mm Knurl (.504")

You don't want a knurl bigger than .505"

.509 will go in with a lot of extra force, but are you putting these in stock axles or forged axles?

Are racing studs mandated by some track rule? If you have stock axles, they are going to break long before factory replacement studs will.

.501 is an interference fit, to add another 8 thousands of an inch is huge

Found some moser studs that are .505 they are on they way from summit. Im using them just cuz i have to run 1 1/4" adapters and i just like piece of mind that they are stronger than stock ones.
