ADVANCED PATENTED DESIGN

round bolts black x 16 2.png

When TPi created the round bolt, they set out to maintain all the physical properties of regular lug bolts, but with improved characteristics. Finished in black to perfectly complement black aftermarket alloy wheels.

The unique flower head design will not slip during torquing enabling a secure and non-slip fitment. It has the added benefit of being a good visual deterrent to thieves.

 

Simply fastened with a standard 17mm socket. No additional key required. 

TUNER BOLTS

Specifically for use with wheels that are drilled with small bolt pockets, our TPi tuner bolts are supplied with a key tool for fastening and removing the bolts. The bolts and overlaying key are just 20mm in diameter and perfect for use where a standard sock won't fit. ​

  • Material - SCM 435, Chrome Vanadium or Chrome Molybdenum

  • Finish - Triple Nickel/Chrome

  • Durability - Triple Nickel/Chrome tested with 96 hours salt. Comprehensive hardness testing.

  • Design - 6 spline tuner, external drive, tapered seat, dual hex socket, sliding design.
