Knurl Size for Wheel Studs?

[Tim Gibbs]

I need to add longer Wheel Studs for my 15" rims. I haven't been able to find the correct Knurl size for the 7/16 20 wheel studs. I would prefer not to have to drill out to a larger size. Does anyone know the standard Knurl size?

Thanks Tim...

Tim search the SAOCA forum... Quite sure Jim Ellis posted the answer to this a ling time ago and a moroso part number for the longer studs.

As a side note Hillman hunter safari ( the wagon/ estate version) has longer studs of same knurl/ pitch .... But probably even harder to find.
