7 SPLINE LUG NUT
Spline Style Wheel Lugs: are the ideal lug nut to fit into the small diameter recesses of newer style rims that cannot fit the standard wrench. Spline lugs require a special adapter for installation and removal which also adds an additional security feature for your wheels.
BULGE ACORN STYLE
Bulge Acorn lug nuts provide more seating surface area than a standard acorn lug nut, and are commonly used for aluminum wheels without a steel insert.
PRECISE BEARING SURFACE
To ensure even distribution of the clamp load and uniform seating of the lug nut to the wheel, our standard for concentricity of the bearing surface to the pitch diameter meets or exceeds O.E.M standards.
