TPI bolts are based on high-grade ASTM 4140 or SCM 440 steel, which is a chrome-vanadium or chrome-molybdenum steel. Each piece undergoes a heat-hardening process to ensure uniform strength. The surface finish is created by triple nickel plating followed by chrome plating, which contributes to its durability. In addition, each production batch undergoes a salt spray test and a tensile test to verify reliability.
