The Socket Set, 1/4" Square Drive (27 piece) is a compact hand tool kit centred on a 1/4" square drive ratchet and a comprehensive selection of small sockets and accessories for light engineering, automotive trim, electrical installation and general workshop maintenance. It is primarily used where access is limited and precision torque control is required, such as tightening small hex head fasteners, servicing carburettors, instrument panels and assembly of precision equipment.

Sockets and accessories in this set are manufactured from chrome vanadium steel (Cr‑V) that has been heat treated for strength and durability and finished with a satin/chrome plating to resist corrosion and simplify cleaning. The ratchet is a reversible 1/4" square drive with a fine-tooth mechanism (typically 72-tooth) to allow minimal swing angle in confined spaces. The set includes predominantly 6-point hex sockets for positive drive on hexagon heads, together with a selection of bit sockets suitable for Allen/grub screws and recessed fasteners. Components are produced to recognised industry manufacturing tolerances in line with standard socket dimensions; they are compatible with common DIN, ISO and BS tooling conventions encountered in engineering and maintenance environments.

Typical applications for this set include precision engineering, light vehicle and motorcycle maintenance, appliance repair, electrical and HVAC fitting, and assembly work in manufacturing or prototyping workshops. The small 1/4" drive is particularly useful for repeatable, low‑torque operations where a larger drive would be unwieldy or where fine control is necessary.

Key benefits include the corrosion-resistant chrome finish, the strength and fatigue resistance of heat-treated Cr‑V material, and the 1/4" drive’s compatibility with a wide range of accessories (extensions, universal joints and sockets). The set’s mix of hex sockets and bit sockets makes it versatile across metric and imperial fasteners commonly encountered in engineering and maintenance.

Duchy Fasteners stocks this 27-piece set alongside individual 1/4" drive sockets and accessories. Sizes are available in metric and mixed sets, with single items and trade packs to suit workshop replenishment or one-off purchases.
