Strength and durability of materials
TPI bolts are manufactured from high-grade steel, specifically a chrome vanadium or chrome molybdenum alloy (ASTM 4140 / SCM 440). This choice of material gives them their durability. In addition, each piece undergoes a heat hardening process. This procedure ensures consistent hardness and strength throughout the entire cross-section of the bolt.
Surface finish and quality control
In addition to their strength, the bolts also have a special surface finish. The gloss black chrome protects the bolt against corrosion. The manufacturer places great emphasis on quality control, which is why every production batch undergoes a salt spray test and a tensile test. These tests verify both the resistance of the surface finish and the mechanical strength of the bolts themselves.
