Attributes:*Material: 40CR-MO*6-Point Socket Size: 64mm*Square Drive Size: 1"*Total Length: 93mm/3.66"*Hexagonal Outer Diameter: 90mm/3.54"*Finish: Black PhosphateWhat Is Included: *1Pcs x 6-Point Impact SocketApplications & Features:--- This impact socket is made of 40CR-MO alloy steel, which offers high hardness, good toughness, strong wear resistance, and can withstand high temperature and the high torque generated by high-pressure impact tools. The surface is phosphated black to prevent corrosion and rust, reduce friction, and is not easy to wear after long-term use--- The 6-point design increases the contact area, distributing force evenly across the fastener plane, reducing wear, and effectively preventing slippage or loosening for greater torque output.
