Fitment and specs

Confirm your adapter takes 9/16"-18 studs by checking its lug nuts before you order. Seat each replacement stud so the knurl is fully engaged and the head sits flush against the plate. Once the wheel is remounted, torque the lug nuts per our torque reference chart and re-torque after 50 to 100 miles.

Common questions

Is 9/16" the same as a 14mm metric stud?
No. 9/16"-18 is an SAE thread, and metric 14x1.5 or 14x2 lug nuts will not seat on it correctly even though the diameters look close. Use only 9/16"-18 lug nuts on these studs.

Which adapters do these fit?
Our 5 lug and 6 lug wheel adapters that are built with 9/16" thread studs. They are not made for the 2-piece conversion adapters, which take their own stud.
