M12 x 1.5 Spline Extended Lug Nuts with Locks - Aluminum
Aluminum spline lug nuts designed to fit M12 x 1.5 studs with integrated lock mechanism. Extended design accommodates aftermarket wheel fitments. Lightweight construction reduces unsprung mass while maintaining secure wheel retention.
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.
