COMPLETE IMPACT SOCKET SET: This complete socket set is heavy duty chrome vanadium and chrome molybdenum, and built with drop forged, heat treated steel to handle the extreme torque of an impact wrench.
6-POINT HEX DESIGN: The 6 PT hex socket design prevents round-off on nuts and bolts under high torque exertion and hammering stress from an impact gun or electric wrench with heavy torque output.
LASER ETCHED SIZES: These impact sockets are each individually identifiable with high-contrast laser etched markings for the easy identification of sizes to keep you working at home or the garage on your car or vehicle.
EXTREMELY LONG-LASTING: Each 3/8-inch drive socket has black phosphate coating for maximum durability, protection, and will last for years in your tool collection at your automotive shop.
