6-Point Design, Made with Chrome Molybdenum Alloy Steel, Jetech 1/2 Inch Drive 21mm Standard Impact Socket, Metric, Heat Treated

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. Cold forging & heat treatment - Cold forging and heat treatment greatly improve the performance of the socket with enhanced hardness, increased wear-resistance and lifespan. Cr-mo alloy steel - cr-mo impact socket features with added strength, higher working temperatures and corrosion resistance.
