Check the listing for details. 3pcs 6-Point Slotted Deep Impact Socket 1/2" Drive 24mm Socket 7.6" Long. Condition: New. Listed at 48.50 USD. 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 included) before use to enhance tightening force and provide additional stability and safety during use. The rounded corners prevent fastener wear and increase torque by applying force to the flat surface of the fastener.
