TPI wheel bolts (10 pcs), R13 ball seat, 17mm flower head, M14×1.5, 28mm, silver
TPI security wheel bolts reliably secure your car's wheels. This set of ten bolts with an M14 × 1.5 thread and 28mm length is made of high-grade steel that undergoes a heat-hardening process to ensure consistent hardness and strength. The bolts have an R13 ball seat and a specific 17mm 'flower' type head, which is tightened with a standard spanner. An advanced surface treatment protects the bolts from corrosion.

Materials and manufacturing for high reliability
TPI bolts are manufactured from high-grade chrome-vanadium or chrome-molybdenum steel (ASTM 4140 / SCM 440). The entire manufacturing process includes heat hardening, which ensures consistent hardness and strength throughout the cross-section of each bolt. Protection against corrosion and external elements is provided by an advanced surface treatment, created by zinc plating or triple nickel plating followed by chrome plating. In addition, each production batch undergoes a salt spray test and a tensile strength test, confirming their reliability even in demanding conditions.
