Durable construction and surface finish
TPI bolts are manufactured from high-grade steel, specifically a chrome-vanadium or chrome-molybdenum alloy (ASTM 4140 / SCM 440). The entire cross-section of the bolt undergoes a heat treatment process, ensuring consistent hardness and high strength. A surface finish of zinc plating or triple nickel and chrome plating provides protection against corrosion and ensures reliable performance. Each production batch is subjected to rigorous tests, including a salt spray test and a tensile test, to verify its reliability.
