Thread each lock in by hand before putting a tool on it, then torque to your vehicle's spec, the same value as your standard bolts; our torque reference chart is a quick reference. Re-torque after 50 to 100 miles of driving.

Common questions

Which shank length do I need?
Match the bolts already on your car. Measure from under the seat to the tip; if that reads about 27mm, this set is the right length. A shank that is too short reduces thread engagement, and one that is too long can bottom out.

Do these fit wheels made for ball seat bolts?
No. These are conical seat locks, and conical and ball seats are not interchangeable even in the same 12x1.5 thread. The seat must match the wheel's bolt holes to center the wheel and hold torque.
