Frequently Asked Questions
Will these work with my OEM wheels, or are they only for aftermarket?
Spline lug nuts require wheels with a spline (female) seat to function. OEM wheels typically use conical seats. Verify your wheel fitment before ordering — most aftermarket performance wheels accept spline nuts, but not all.
Do these need any special tools to install or remove?
A standard lug wrench or socket that fits M12 works fine. The spline mechanism is passive — no special tools required. Just hand-tighten first, then torque to your vehicle's specification per the service manual.
What happens if one lug nut gets damaged — can I replace just one?
You can replace individual nuts, but for safety and appearance, we recommend replacing them in complete sets. This keeps all wheel fasteners uniform in age and condition.
