7/16"-20 Lug Nuts

7/16"-20 Lug Nuts

Our complete 7/16"-20 lug nut selection: 7/16 inch thread diameter with 20 threads per inch. This is the go-to size for classic GM muscle-car wheels, stocked here in mag, Cragar Style mag, acorn, bulge acorn, ET and spline drive styles.

This size is commonly found on classic GM cars from the muscle-car era, including many Camaro, Chevelle and Nova applications, and on vintage aftermarket mag wheels. Always verify your thread size before ordering. Double-check your size against our wheel fitment guide if you are not sure.

7/16"-20 lug nut common questions

Common questions

What does 7/16"-20 mean? The stud measures 7/16 inch across with 20 threads per inch. Some listings shorten it to 7/16.

Which nuts fit Cragar-style wheels? Mag-seat nuts with a washer and the correct shank length. Our Cragar Style mag lug nuts in this collection are made for that design.

How tight should they be? Classic-car specs vary; check your restoration manual and our torque chart before installation.

Also browse 1/2"-20 lug nuts, 9/16"-18 lug nuts and all wheel lug nuts. For tightening specs, check our torque reference chart.
