Fitment and specs
- Thread size: 12x1.25
- ET spline drive body
- Slim tuner profile for tight lug pockets on aftermarket wheels
- Black finish
- Installs with a spline drive key rather than a standard hex socket
These thread onto 12x1.25 studs and turn with a spline drive key seated fully into the splines. Snug each one, then torque to your vehicle's factory specification using the torque reference chart, and re-torque after 50 to 100 miles.
Common questions
Do I need a special tool to install these?
Yes. The ET spline drive turns with a matching spline key instead of a normal hex socket, which also adds a bit of theft resistance. Make sure the key fully engages the splines before applying torque.
Will these fit my wheels?
They are 12x1.25 thread with a conical seat. Confirm the pitch and seat style match your wheels by comparing to a lug nut currently on your car, or check the thread size stamped on your studs.
