TPi locking bolts set the highest standards in the industry. Cold-forged locking bolts can achieve 12.9 Class in strength, are coated with 96 hours Triple Nickel Chrome finish and are 100% manually and visually tested.

TPi locking bolts are conveniently packed in TPi clamshell with 4 locking bolts, 1 key and 1 Key ID Card.

TPi's anti-theft wheel lock systems fasten wheels, at the same time protecting them from theft.

All wheel locks function like a regular lug nut, but require a special key tool for installation and removal.


  • Narrow Groove Patterns - resistant to the intrusion of lock removal tools.

  • Heat Treated - Every locking bolt undergoes heat treatment reaching the hardness required for it's unsurpassed level of security.

  • Perfect fit - Extreme accuracy in tolerances give a perfect fit every time.


Our TPi Polarised lock bolts have all the quality features of our regular bolts, but have a standard hex for fastening, and have the unique neo-chrome polarised finish from that will not fade or tarnish. These perfectly match our Polarised hex bolts. Give your wheels that special touch.
