The 22mm 12-point socket with a 3/4in square drive is a hand socket designed for tightening and loosening 22 millimetre hex fasteners where high torque and quick engagement are required. It is intended for heavy-duty maintenance and assembly tasks where a robust 3/4in drive ratchet, breaker bar or torque wrench is used to apply significant turning force to metric fasteners.

This socket is manufactured from chrome vanadium steel (Cr‑V) and is heat-treated to improve tensile strength and wear resistance for repeated workshop use. The exterior is bright chrome plated to provide corrosion resistance and an easy-to-clean surface finish. The socket uses a 12‑point (double hex) internal profile which permits more frequent re-engagement positions in confined spaces compared with a 6‑point socket; the square drive is 3/4in (19.05mm) to match standard heavy-duty ratchets and accessories. Thread type is not applicable for this product as it is a push‑on socket; it is compatible with square drive tools conforming to common DIN/ISO/BS drive-fit tolerances for hand sockets.

Typical applications include commercial vehicle maintenance, agricultural machinery repair, construction plant servicing, and general industrial maintenance where large metric fasteners are encountered. The socket’s 12‑point profile is useful for quickly locating the fastener in limited access situations and for use on both 12‑point and hexagonal fasteners, while the 3/4in drive handles higher torque requirements than smaller drive sizes.

Key benefits are notable corrosion resistance from the chrome finish, the strength and longevity provided by chrome vanadium construction and heat treatment, and broad compatibility with standard 3/4in drive accessories. For maximum torque and to reduce the risk of rounding older or soft fasteners, a 6‑point socket or torque‑rated tooling may be preferred; this Draper hand socket is not intended for use with impact wrenches—use impact sockets for those applications.

Duchy Fasteners stocks this Draper Tools Group D 22mm 12‑point socket (DR10149) individually and in bulk packs. We also carry metric sockets across common drive sizes (1/4in, 3/8in, 1/2in and 3/4in) and a full range of sizes to suit workshop and industrial needs.
