Materials Overview
Made of high-quality 304 stainless steel and reinforced through A2-70 cold hardening treatment, it offers high tensile strength, structural toughness, and corrosion resistance. It resists rust in damp workshops, outdoor atmospheric environments, and in fresh water and weakly acidic or alkaline environments, thereby addressing the oxidation failure issues that carbon steel lock nuts experience in damp and outdoor settings. The standard Hex Lock Nut is compatible with all conventional wrenches, sockets, and pneumatic tightening tools, facilitating assembly and maintenance.
