This product is a 12 mm 6‑point socket with a 1/4in square drive, intended for use with 1/4in ratchets, torque wrenches, extensions and other hand tools to tighten or loosen M12 hexagonal fasteners and other 12 mm hex heads in confined spaces. Its primary use is hand‑torque fastening where a compact, accurate fit to the fastener is required.

The socket is manufactured from chrome vanadium (Cr‑V) steel, heat treated for strength and toughness and finished with a bright chrome plate to give corrosion resistance and ease of cleaning. Head type is 6‑point (hex) to engage the flats of a hex fastener, reducing the risk of rounding compared with 12‑point designs. Drive type is 1/4in (1/4dr) female square recess, compatible with industry standard 1/4in drive tools. Thread type is not applicable to this item because a socket connects by its square drive rather than by threads. The product is produced to meet recognised DIN/ISO/BS dimensional and drive‑interface standards for hand sockets (for example typical references include DIN and ISO specifications for square drive sockets), ensuring compatibility with other standard 1/4in tools and accessories.

Typical applications include light automotive and motorcycle maintenance, bicycle repair, instrumentation and electronics assembly, plant maintenance, HVAC work and general engineering where small metric fasteners are used. The compact 1/4in drive and 6‑point geometry make it particularly useful in tight spaces and for tasks requiring precise torque control with a small torque wrench or ratchet.

Key benefits include reliable engagement with 12 mm hex heads to reduce fastener damage, corrosion protection from the chrome finish, and the mechanical strength of heat‑treated chrome vanadium construction for repeated hand use. Note that this is a hand tool socket and is not designed for use with impact wrenches; use designated impact sockets for pneumatic or high‑torque impact applications. The socket is compatible with common 1/4in extensions, universal joints and bit adapters.

Duchy Fasteners stocks metric 6‑point sockets in single sizes and trade bulk packs; our socket range commonly covers 4 mm up to 19 mm and is available as individual pieces, bulk packs or in sets. Product code DR12477.
