This is a 24 mm bi‑hex (12‑point) socket with a 1/2 inch square drive, designed to engage hexagonal and 12‑point fasteners where greater re‑engagement angles and improved access are needed. Its primary use is for loosening and tightening bolts and nuts with a 24 mm head using 1/2" drive ratchets, torque wrenches, breaker bars and extensions in workshop and on‑site maintenance environments.

The socket is manufactured from chrome‑vanadium steel (Cr‑V) that has been heat treated and tempered to provide the required toughness and wear resistance for repeated use. The external surface is polished and chrome plated to provide corrosion resistance and an easy‑clean finish. The product conforms to recognised DIN, ISO and BS hand tool socket standards for dimensions and drive interface to ensure compatibility with common square‑drive tools. It features a bi‑hex 12‑point internal profile and a 1/2in square drive recess; the 12‑point geometry allows engagement at 30° increments, which is useful in confined spaces or when rapid repositioning of the ratchet is necessary.

Typical applications include automotive repair and servicing, commercial vehicle maintenance, agricultural and plant machinery servicing, industrial assembly and mechanical engineering. The 24 mm size is commonly used on suspension, engine and transmission fastenings as well as chassis and structural bolts. The socket is suitable for use with torque wrenches for controlled tightening, subject to observing the torque tool manufacturer’s capacity limits.

Key benefits of this bi‑hex socket include improved access and faster re‑engagement compared with 6‑point sockets in tight locations, broad compatibility with both 6‑ and 12‑point fasteners, robust material construction for longevity, and a chrome plated finish to resist corrosion in workshop environments. Its 1/2in drive makes it compatible with a wide selection of ratchets, extensions and breaker bars.
