  5. Unique driver bit engages very shallow keyway profile fins leaving nothing for thieves to grip onto
  6. Outer shroud spins freely frustrating thieves
  7. Hardened, heat-treated steel

Security Cap - Tough Exterior

More than meets the eye. A threaded, 200 ft-lb torqued security cap is only the beginning of the security features. This first barrier must be removed with the proprietary tri-pin end of the included driver bit. The asymmetrical pin pattern acts as a disguised security feature.

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.
