This is a 1/2" square drive metric socket set intended for general workshop use where a mid‑to‑heavy torque hand drive is required, such as vehicle servicing, plant maintenance and mechanical assembly. The 30-piece set gives a comprehensive spread of metric sockets together with essential accessories so you can tackle hex fasteners from shallow recessed bolts to deeper studs using a single 1/2" drive ratchet system.

The sockets are manufactured from chrome vanadium steel (Cr‑V), heat treated and quenched to provide the toughness and yield strength demanded in workshop environments. Sockets are supplied in a 6‑point (hex) profile to give maximum contact on wrench flats and minimise rounding of fasteners. All components have a polished chrome plated finish to resist surface corrosion and ease cleaning. The set conforms to common DIN and ISO dimensional standards for sockets and drive fittings and meets typical BS tolerances for fit and concentricity, ensuring compatibility with other 1/2" drive tooling.

The drive type is a 1/2" (12.7 mm) square drive, compatible with industry standard ratchets, breaker bars and torque wrenches. The set contains a mix of shallow and deep sockets to suit head type and access, plus hand‑tool accessories commonly required in a 1/2" set: a ratchet handle, extension bars and a universal joint for awkward angles. These are intended for hand tool use; they are not impact rated and should not be used with pneumatic or electric impact tools unless specifically marked as such.

Typical applications for this socket set include automotive repair and servicing, agricultural and construction machinery maintenance, engineering workshops and facilities management. The key benefits are the material strength of chrome vanadium, the corrosion protection of the chrome finish and the wide compatibility offered by standard 1/2" drive sizes and DIN/ISO dimensional conformity. The 6‑point profile reduces fastener damage while the inclusion of both shallow and deep sockets improves flexibility on a wide range of bolt types.

Duchy Fasteners stocks this 30-piece Draper Tools Group D set (DR16466) and also supplies individual metric sockets in a range of sizes and pack quantities, from single pieces up to complete sets for workshop and trade use.
