This is a 32mm bi‑hex (12‑point) socket designed for manual use with 1/2in square‑drive ratchets and breakers. Its primary purpose is to engage 12‑point head bolts and nuts where additional indexing positions are required or where access is restricted, providing positive engagement at 30° increments for quicker positioning on fasteners.

The socket is manufactured from chrome‑vanadium (Cr‑V) alloy steel, heat treated and tempered to provide the toughness and strength required for hand tool service. The typical hardness range after treatment is approximately 48–54 HRC, giving good resistance to deformation under torque. The external finish is polished chrome plating to resist corrosion and ease cleaning in workshop environments. The socket features a standard 1/2in (12.7mm) square drive with a detent hole and spring ball retention to secure it to ratchets, extensions and spinner handles. Dimensional form and 12‑point geometry conform to common DIN/ISO/BS socket standards used in industry to ensure compatibility with mating fasteners and tool accessories.

Typical applications include automotive and commercial vehicle maintenance, plant and machinery servicing, agricultural and construction equipment work, and general industrial assembly. The 12‑point profile is particularly useful where fasteners are closely spaced or where repeated rapid indexing is needed, and is widely used by mechanics, maintenance engineers and service workshops working on cylinder heads, transmission components and heavy‑duty fastenings.

Key benefits of this 32mm bi‑hex socket are its corrosion‑resistant chrome finish, the strength and resilience provided by Cr‑V heat treatment, and broad compatibility with standard 1/2in drive tooling. The 12‑point form reduces the need for precise alignment compared with 6‑point sockets, while still providing secure torque transfer on suitably shaped fasteners.
