Protector Nut – Strong AND Unique

The strength of the Structural Nut assembly is the Protector Nut. The steel hardness and shallow keyway geometry gives would-be thieves nothing to grab onto. The perfectly matched driver bit locks onto the tapered keyway fins allowing incredibly high torque.

Enigma Key Coding – 131 billion keyway variations. These twists and tapers of the keyway can only be replicated by the same machine that created the original key-code. Any counterfeit wrench can not engage sufficiently to apply the required breakout torque.
