Fitment and specs
- Thread size: 9/16"
- Drive style: duplex spline drive
- Requires a matching spline key to install and remove
- Match to your vehicle's known thread size and stud pattern
Seat the spline key fully into the nut and your socket before turning so the drive points stay sharp, then tighten to your vehicle's factory specification using the torque reference chart. Re-torque after 50 to 100 miles so the nuts stay tight as they settle.
Common questions
Do these need a special tool?
Yes. Spline drive nuts turn with a spline key instead of a standard hex socket, which also makes them harder to remove without the matching key on hand.
How do I confirm my thread size?
These are cut for a 9/16" thread. Check it against a nut already on your vehicle or your vehicle's known stud thread.
