Kincrome’s range of impact sockets are manufactured from Chrome Molybdenum (Cr-Mo) and feature a black phosphate finish for superior corrosion protection, laser etching for easy drive size identification and Peripheral Drive™ technology. Peripheral Drive™ provides greater torque by relocation the load to the flat sides of a fastener, this allows for greater surface area contact and prevents “rounding off” of fasteners. Hex 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.
