This is an 8 mm deep 12‑point socket with a 3/8 inch square drive, designed for reaching recessed metric fasteners and for use with 3/8" drive ratchets, extensions and torque wrenches. Its primary use is to access bolts and studs where a standard shallow socket cannot reach, and the 12‑point internal profile allows quicker alignment onto the head in confined spaces.

The socket is manufactured from chrome vanadium steel (Cr‑V) and is heat treated to provide strength and durability. It features a bright chrome plated finish to resist corrosion and ease cleaning. The internal 12‑point (double‑hex) profile conforms to standard metric socket dimensions for interchangeability with metric fasteners, and the 3/8" (9.5 mm) square drive is compatible with commonly used hand tools in line with recognised DIN/ISO/BS drive conventions. A detent hole and chamfered entry ensure secure fitment on ratchet adapters and extensions.

Typical applications include automotive workshop maintenance, light and heavy engineering, agricultural machinery service, plant maintenance and assembly work where access is limited or fastener heads are recessed. The 12‑point form is particularly useful when working on fine‑threaded or multi‑faceted fasteners, and it allows engagement at more angles compared with a 6‑point socket—useful in tight spaces—while still providing adequate torque for general service tasks.

Key benefits of this 8 mm deep 12‑point socket are its corrosion resistance owing to the chrome plating, robust material construction from chrome vanadium for long service life, and the universal 3/8" drive compatibility with a wide range of ratchets and accessory tools. The 12‑point profile offers faster alignment and easier re‑engagement on fasteners; however, for maximum torque on heavily rounded or high‑torque applications, a 6‑point socket may be preferable.
