This is a 12 mm, 6-point hand socket designed to be used with a 1/2" square drive ratchet, breaker bar or torque wrench for the removal and installation of hexagonal nuts and bolts. Its primary use is to provide secure engagement with metric fasteners in medium- to heavy-duty maintenance, repair and assembly tasks where a robust drive connection and high torque transmission are required.

The socket is manufactured from chrome vanadium steel (Cr-V), heat-treated and tempered to give the strength and toughness needed for repeated workshop use. The internal profile is a 6-point (hexagon) design which seats fully on the flats of a fastener to reduce rounding and distribute load across a larger contact area than a 12-point alternative. The socket accepts a 1/2" (12.7 mm) square drive and is compatible with British and international ratchets and torque tools; it is produced to conform with common hand-tool dimensional and fitment criteria from recognised standards bodies (DIN/ISO/BS) for sockets and square drives.

Finish is bright chrome plating with a polished exterior to resist corrosion and ease cleaning; the plated surface also reduces the risk of rust in workshop and vehicle environments. Threading is not applicable to this product beyond the machined drive recess; the socket is retained on the drive tool by the standard detent ball or pin of the ratchet or extension used.

Typical applications include automotive repair, commercial vehicle maintenance, industrial machinery servicing, plant maintenance and agricultural equipment work. The 6-point geometry is particularly suited to older or high-torque fasteners and situations where repeat tightening and loosening could otherwise damage bolt heads. Key benefits are the socket’s corrosion-resistant chrome finish, strength from Cr‑V construction and heat treatment, and its compatibility with 1/2" drive torque tools for reliable torque transfer and long service life.
