Not correct knurl width

The knurl length was fine for my rotors. However, I used the standard/recommended drill bit for these studs and they just fall right out. Even after user an air hammer to get them to seat, they would still fall out. If you want nice lug nuts though, those are nice.

Arrives in 4 bags and boxes of 5 studs per. Best price I've found anywhere, and they have been thoroughly crash tested. Lug nuts are double sided.
