5-Lug M12 x 1.5 Install Kit

This kit contains the wheel locks and lug nuts required to fit four wheels. It uses a SplineDrive profile that matches the narrow recesses found on tuner-style wheels. The one-piece locks need the supplied key tool for installation and removal.

Closed-end design reduces mass

Each nut is 30% lighter than a comparable socket-style lug nut. The closed-end construction adds stud engagement and a larger seating surface. Chrome plating is guaranteed for life against rust, chips and peeling.

Key tool and computer-generated patterns

A unique key tool is included so only the owner can remove the locking nuts. The computer-generated key patterns provide an effectively infinite number of combinations. All components are manufactured in the USA to meet or exceed OEM safety standards.

Questions about this item

How do I install the M12 x 1.5 SplineDrive lug nuts and what step is often missed?

Thread each lug nut by hand onto the wheel studs to avoid cross-threading, then tighten with the included spline key in a star pattern to the vehicle manufacturer's torque specification; the step often missed is hand-starting every nut before using any tool.

What maintenance or replacement will the chrome SplineDrive lug nuts need over time?

The chrome plating is guaranteed for life against rust, chipping and peeling, so no finish maintenance is required; inspect the spline grooves and cone seats whenever wheels are removed and replace any lug nut showing thread damage or deformation.

What is the first limit reached when the SplineDrive lug nuts are used under sustained heavy loads?

The limiting factor is the M12 x 1.5 thread engagement and the wheel stud's tensile strength; the lug nuts are machined to meet or exceed OEM safety standards, so the stud will yield before the nut fails.
