They are made from chrome-vanadium or chrome-molybdenum steel and undergo a heat hardening process, which ensures their strength. The bolts have a 60° conical seat, an M14×1.5 thread and a length of 40mm. The flower-shaped head is tightened with a standard 17mm wrench. This pack contains ten bolts.

Durable materials and manufacturing

TPI bolts are manufactured from ASTM 4140 or SCM 440 steel, which corresponds to a chrome-vanadium or chrome-molybdenum alloy. The heat hardening process ensures consistent hardness and strength throughout the entire cross-section of the bolt. The surface finish of triple nickel and chrome plating increases their service life. Each batch undergoes a salt spray test and a tensile test, which verifies their resistance to corrosion and mechanical stress.
