This is a 1 1/16in AF, 12-point (bi‑hex) socket with a 1/2in square drive, supplied in bulk for professional workshops and maintenance departments. Its primary use is to fasten and remove 12‑point and hexagonal nuts and bolts where a 1 1/16in across‑flats size is required, and where a 1/2in drive ratchet, breaker bar or torque wrench provides the drive torque.

The socket is manufactured from chrome‑vanadium (CrV) alloy steel that has been heat treated and tempered to meet common industrial hand‑tool strength requirements. It is finished with a bright chrome plate to resist corrosion and simplify cleaning. The 12‑point geometry allows twice as many engagement positions compared with a 6‑point socket, making it quicker to locate on fasteners in confined spaces. The socket is produced to fit the industry standard 1/2in square drive and conforms to commonly accepted DIN/ISO/BS sizing and drive interface conventions for interchangeability with other 1/2in hand tools.

Typical applications include automotive repair and restoration, commercial vehicle and plant maintenance, industrial assembly, agricultural machinery servicing and mechanical engineering workshops. The 12‑point profile is particularly useful on multi‑flat bolts and on fasteners where access is limited; it also accommodates 6‑point (hex) heads when rapid re‑positioning is required, although 6‑point sockets remain preferable for sustained high torque on rounded or damaged fasteners.

Key benefits are its material toughness, the protective chrome finish which improves corrosion resistance in workshop and outdoor environments, and the broad compatibility with 1/2in drive tools and accessories (extensions, universal joints, torque wrenches). The 12‑point design speeds engagement and reduces the need for repositioning in tight spaces, while the CrV construction provides long service life under normal workshop loads.
