Kincrome’s range of TORX® impact sockets are manufactured from Chrome Molybdenum (Cr-Mo) and feature a black phosphate finish for superior corrosion protection and laser etching for easy drive size identification. Chrome Molybdenum is an industrial grade material designed for impact and extreme torque applications. ToRX® Impact sockets are designed to withstand the high torque and force associated with impact tools in repetitive application and can be used on stubborn fasteners. IMPORTANT: Only Impact Sockets should be used on air or electrically operated power tools. NEVER use silver Chrome Vanadium Steel (Cr-V) Sockets which can shatter and cause personal injury.
