This product is a 22 mm impact socket with a 1/2-inch square drive, designed for use with pneumatic and electric impact wrenches, rattle guns and torque multipliers. Its primary purpose is to transmit the high, shock-loaded torque produced by impact tools to hexagonal fastener heads reliably and safely—where a standard chrome-vanadium hand socket would be likely to fail.

The socket is manufactured from chrome-molybdenum (Cr-Mo) impact-grade alloy steel, heat-treated and tempered for toughness and fatigue resistance. It is supplied with a black phosphate/oxidised finish to reduce surface corrosion and control glare in workshop environments. The profile is a 6-point (hex) head for positive contact on bolt flats and reduced risk of rounding. Drive connection is a 1/2" (12.7 mm) square recess compatible with industry-standard 1/2" impact tool drives. The socket is produced to DIN/ISO dimensional profiles for metric sockets and is machined to meet common BS tolerance bands for drive fit and socket depth to ensure interchangeability with other 1/2" tools and accessories.

Typical applications include automotive and heavy vehicle maintenance, agricultural machinery repair, plant and machinery servicing, construction equipment overhaul and general industrial maintenance where high torque and repeated impact loading are routine. Workshops, fleet service depots and mobile engineers favour impact sockets for wheel nuts, suspension work, excavator and loader maintenance and other high-torque fastenings.

Key benefits of this 22 mm impact socket are its superior toughness under impact loading compared with hand sockets, compatibility with standard 1/2" impact tools and a protective finish that reduces corrosion in workshop and outdoor use. The 6-point profile provides secure engagement on hex fasteners, reducing slippage and damage to bolt heads. Because it is made from Cr-Mo alloy and heat-treated, the socket resists cracking and chipping under repeated use.

Duchy Fasteners stocks this 22 mm impact socket individually and in bulk quantities; we also carry a comprehensive metric range in 1/2" drive from small to large sizes to suit workshop and fleet requirements. Check available pack sizes and bulk discount options when ordering.
