Common questions

What are these meant to fit?
Aftermarket wheels with a 60 degree conical seat on 7/16" studs. The listing calls out aftermarket rims for classic Chevys, including the Bel Air, 1968-82 Corvette, 1977-87 Impala and Caprice, and 1964-81 El Camino.

Can I run them on stock wheels?
Often not. Even if the 7/16" thread matches, a factory wheel's seat pocket is frequently too small for this nut style to seat fully and build safe clamping force. Verify your wheel's seat type and size first.
