Cr-Mo ALLOY STEEL - Cr-Mo impact socket features with added strength, higher working temperatures and corrosion resistance. It's much stronger to stand greater impact force than chrome vanadium ones. COLD FORGING & HEAT TREATMENT - Cold forging and heat treatment greatly improve the performance of the socket with enhanced hardness, increased wear-resistance and lifespan. 6-POINT SOCKET OPENING - 6-point design provides an exact and snug fit, allowing it to apply more torque on the fasteners and avoid slipping off. RADIUS CORNER DESIGN - The lifespan of both the fastener and socket will be greatly prolonged with the torque distributed to the inwall. BLACK PHOSPHATING - A fine and dense coating brings more corrosion and wear resistance for longtime use.
