Groz ISKT/H/1-2/21 Hex Impact Socket, 1/2 in Drive, 21 mm

This 21 mm Groz hex impact socket runs on a 1/2" drive. Chrome Molybdenum Steel construction and heat treatment give it the hardness, tensile strength and torque resistance Groz builds into its impact range, and a chamfered opening lets it seat onto an impact tool without fuss; a pin hole takes the retaining pin. Groz finishes the socket in Black Oxide for corrosion resistance and quick visual identification against ordinary sockets, with the size and branding laser-etched on. Groz suits this range to construction, industrial and agricultural work.
