Advanced Patented Design

When we decided to create the Round Bolt, we wanted it to maintain all the physical properties of our regular lug bolts, but with improved characteristics.

A Smartly Designed Key & Dual Hex Key

One key can be applied on both the locks and the regular tuner lug bolts, making it more user-friendly and convenient for customers to keep one key only.
Dual Hex Key is provided for greater application coverage, which matches the vehicle's original equipment lug wrench.

Well-Designed Bolt Cover Available

With Bolt Cover, it’s hard for thieves to identify that there is a lock on your wheel, which assures you peace of mind. Bolt Cover is developed to cover both the External Locking Bolts and the Round Bolts. The inside of the lock bolt cover has the pattern design, but on the outside it looks like a regular hex. When the bolt covers are placed on the fasteners, it’s hard to tell lock from bolt.

Quick Identification & TPI Logo Marked
