Cr-Mo ALLOY STEEL - Cr-Mo deep 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.
EXTRA DEPTH - Provide more space to accommodate longer bolts and wider applications to facilitate your work.
RADIUS CORNER DESIGN - The lifespan of both the fastener and socket will be greatly prolonged with the force distributed to the inwall.
BLACK PHOSPHATING - A fine and dense coating brings more corrosion and wear resistance for longtime use.
