This is a 12‑point socket with a 1/2" (1/2 drive) square recess, designed to engage fasteners with a 12‑point (bi‑hex) head profile. Its primary use is for heavy‑duty tightening and loosening of nuts and bolts where a 1/2" drive ratchet, breaker bar or torque wrench is used, particularly where access is restricted and you need finer indexing than a 6‑point socket allows.

The socket is manufactured from chrome‑vanadium (Cr‑V) steel and is heat treated to give good tensile strength and wear resistance. The exterior is bright chrome plated to resist corrosion and to make cleaning and identification easier in workshop environments. The head type is 12‑point (bi‑hex) and the drive type is a 1/2" (12.7 mm) square drive recess, compatible with standard 1/2" ratchets, extension bars and torque tools. The component is produced to common industry dimensional standards for hand sockets, meeting widely used DIN, ISO and BS requirements for 12‑point sockets so it fits conventional fasteners and tools used across Europe and the UK.

This 12‑point 1/2" drive socket is typically used in automotive maintenance and repair, commercial vehicle workshops, agricultural machinery servicing, plant maintenance and general mechanical assembly. The 12‑point profile permits engagement on fasteners in tighter spaces and allows 30° indexing, which helps when movement is limited. It is also suitable where repeated removal and refitting is required and where access to bolt corners rather than flats is necessary.

Key benefits include the material’s inherent strength and fatigue resistance from chrome‑vanadium construction, enhanced corrosion protection from the chrome finish, and broad compatibility with standard 1/2" drive tooling. The 12‑point form reduces the need for perfect alignment and speeds up work in confined areas while maintaining sufficient contact area to avoid rounding fasteners in most workshop applications.
