Lockable Wheel Nuts

To protect valuable alloy wheels against theft, a lockable wheel nut was developed and offered as a set of four.

Within a set, all four nuts have the same locking mechanism.

The part consists of a special nut with an axial bore, a sleeve with a built-in locking cylinder, and a sealing cap. When locked, the locking cylinder's tumblers engage grooves within the nut's axial bore, preventing the sleeve from being removed. Since there is no frictional connection between the hexagon and the sleeve, it is not possible to loosen the nut by turning the sleeve.

The slight additional weight compared to a standard nut generally does not require rebalancing of the wheels.

The lockable wheel nut is suitable for all 5-hole Porsche rims.
