I am having .486 knurl dia. ARP studs pressed in my stock gm hubs which measure roughly .45 what dia. should I have the hubs drilled to to get a positive press.
How many thousands smaller is standard?
What drill size do I need for my wheel studs?
To determine what drill size you need for your wheel studs, you will need to know your axle/hub material and the wheel stud knurl diameter. If your axle/hub material is cast iron/steel your drill size will be .005˝ less than the knurl diameter. If your axle/hub material is aluminum, your drill size will be .007˝ less that the knurl diameter.
