Re: Wheel studs
.
Well, I just learned a little something. "ARP" wheel stud folks say:
"For steel and cast iron hubs, the hole should be 0.006-0.016˝ smaller than the Knurl Diameter."
The "knurl diameter" is measured on the outside of the knurled splines.
SOME wheel studs have an underhead radius. Each hole must be chamfered 0.025˝ to clear the underhead radius and prevent stud failure.
Just sayin'! DD
