Review on 🦍 Gorilla Automotive 21681BC Small Diameter Wheel Locks in Black Chrome - Thread Size 1/2 by Brian Graham

These are ideal for small diameter external "slotted" lug nuts, the wrench provided can also remove regular keyless lug nuts. They work by changing the thickness of the spline and skipping some to create a lock that can only be set and set/uninstalled with the appropriate key. They also have a G stamp on the top so you can tell which lock it is compared to other nuts.
