Contents: A McGard Tuner lock set consisting of 4 tuner lock nuts + 1 key

McGard tuner lock nuts are designed for narrow shank rims. Here the outer diameter of the bolts and the wrench has been reduced a bit. McGard's Tuner products meet all the requirements of the automotive industry. European automakers usually use bolts to secure the wheels.

Manufacture in a cold extrusion process ensures that the lock nuts correspond to strength class 10.9.
Tuner locknuts follow a special process in which the locknut is hardened to a hardness of 46-54 HRC. The lock nuts are coated with Geomet. This coating ensures the color is guaranteed when the lock nuts are loosened and tightened several times.

Furthermore, this coating offers excellent protection against corrosion and difference.
