Our impact sleeves are made of 45# steel and undergo secondary heat treatment, giving them high hardness, high strength, toughness, and excellent oxidation resistance, enabling them to withstand the high torque generated by high-pressure impact tools. The surface is phosphated, providing excellent corrosion resistance, wear resistance, and rust prevention, ensuring they are not easily worn in high-friction environments.Each socket features a pinhole base design, allowing for the insertion of a locking pin (NOT inluded) before use to enhance tightening force and provide additional stability and safety during use.
