This product is a 10 mm, 12‑point hand socket with a 3/8in square drive, designed for use with 3/8in ratchets, torque wrenches, extensions and universal joints. Its primary use is the accurate engagement, tightening and removal of hexagonal fasteners in workshop and maintenance environments where a compact entry angle and multiple indexing positions are required.

The socket is manufactured from chrome‑vanadium (Cr‑V) steel that has been hardened and tempered to provide improved torsional strength and fatigue resistance. It is supplied with a bright chrome plated finish to aid corrosion resistance and facilitate cleaning. The 12‑point head form allows easier alignment on fasteners and can engage hex heads at 30° intervals, making it useful in confined spaces where full rotation is limited. The socket features a standard 3/8in (9.5 mm) square drive recess compatible with DIN/ISO/BS drive size conventions for hand sockets. As a hand socket it is not intended for impact tools; for impact use choose purpose‑made impact sockets with a matt phosphate finish.

Typical applications for this 10 mm 12‑point, 3/8in drive socket include light to medium automotive repair, plant maintenance, mechanical and electrical installation, HVAC servicing and general engineering workshops. The 12‑point geometry is particularly useful on fine‑pitch or shallow hex heads and on fasteners where quick indexing is beneficial. Industries that commonly use this style of socket include automotive, industrial maintenance, agricultural machinery servicing and facilities management.

Key benefits of this socket are its corrosion resistant chrome finish, the strength provided by heat‑treated chrome‑vanadium construction and broad compatibility with standard 3/8in drive hand tools and socket accessories. The accurate internal profile reduces the risk of rounding fastener corners and permits reliable torque transfer within the recommended hand‑tool range.
