The 25 mm 1/2" drive socket (Draper Tools Group D, DR33418) is a metric hex socket designed to be used with 1/2" (12.7 mm) square drive ratchets, torque wrenches and breaker bars to tighten or loosen 25 mm headed nuts and bolts. Its primary use is in general maintenance and repair tasks where a robust, accurately sized socket is required to transmit torque without damaging fastener heads.

This socket is manufactured from heat-treated chrome vanadium (Cr-V) steel and finished with a bright chrome plate to resist corrosion and simplify cleaning. The internal profile is a 6-point (hex) configuration to give maximum contact with the flat faces of a nut or bolt head and to reduce the risk of rounding under heavy loads. The socket accepts a standard 1/2" square drive tooling interface and is produced to industry-standard drive and dimensional conventions so it will fit securely to most 1/2" drive ratchets and extensions used in professional workshops.

Typical applications include automotive and commercial vehicle maintenance, agricultural machinery servicing, plant and machinery assembly, and general engineering workshops. The 25 mm size is common on suspension, drivetrain and structural fastenings on cars, vans and light commercial equipment, as well as on industrial machinery where larger metric head sizes are used.

Key benefits of this socket are its corrosion-resistant chrome finish, the strength and toughness of chrome vanadium construction, and the 6-point profile that improves torque transfer and reduces fastener damage. Compatibility with 1/2" drive torque tools makes it suitable for use with calibrated torque wrenches for controlled tightening or with breaker bars for high-torque removal, within the working limits of hand tools.

Duchy Fasteners stocks this socket individually and as part of Draper wrench and socket sets; we carry a full metric and imperial range in 1/4", 3/8" and 1/2" drive formats and offer single items or multi-piece packs to suit workshops and professional users.
