Does anyone know the Thread pitch specs on the wheel bolts? My local tire guy sell screw in studs, but needs that info.

Thanks

Are you talking about using the studs that are double threaded and tighten with a allen wrench and loctiite'd in? VW shops sell them, but I really won't do it. They are cheap cast studs, not cut treads on tool steel. Years ago, I twisted two of them off on the same wheel by hand tighting them.
