LOCKING BOLTS

TPi set out to create a regular bolt for the luxury and European market, and went far beyond industry standards to bring a product to the market that is unmatched in quality.

Puzzle locking bolts

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

The narrow groove resists the intrusion of lock removal tools into the pattern.

Heat Treated

Every locking bolt undergoes heat treatment reaching the hardness needed for it's unsurpassed level of security.

Perfect fit

Extreme accuracy in tolerances
