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

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

Extra depth - provide more space to accommodate longer bolts and wider applications to facilitate your work. Black phosphating - A fine and dense coating brings more corrosion and wear resistance for longtime use. Radius corner design - the lifespan of both the fastener and socket will be greatly prolonged with the force distributed to the inwall. It’s much stronger to stand greater impact force than chrome vanadium ones.
