This is a Draper 7/16in AF bi‑hex socket with a 1/2in square drive, designed for removing and tightening imperial hex fasteners where space or re‑engagement speed is important. The bi‑hex (12‑point) profile allows quick alignment on nut corners and is particularly useful when working with fasteners in confined positions or where repeated engagement is required.

The socket is manufactured from hardened chrome‑vanadium (Cr‑V) steel and is chrome plated to resist corrosion and ease cleaning. The 1/2in drive is a standard square fitting to suit 1/2in ratchets, breaker bars and extensions. As a hand socket it complies with common dimensional and material expectations for hand sockets and is compatible with DIN/ISO/BS hand‑tool conventions for drive sizes and across‑flats dimensions (bi‑hex 12‑point profile). This is a non‑impact socket; it has been heat treated for hand‑tool torsional strength but should not be used on pneumatic or electric impact tools unless specifically marked as impact‑rated (typically Cr‑Mo construction and a matt finish).

Typical applications include automotive and light commercial vehicle maintenance, agricultural machinery servicing, general engineering maintenance, plant and machinery refit, and workshop use where imperial fasteners are still found. The 12‑point form is especially helpful on studs, thin‑walled nuts and fasteners with limited swing for ratchets, enabling quicker re‑engagement than a 6‑point socket while still providing good torque transmission on undamaged hex corners.

Key benefits of this socket are its corrosion‑resistant chrome finish, the strength and wear resistance of Cr‑V steel, and wide compatibility with standard 1/2in drive toolsets. The bi‑hex profile gives greater accessibility in tight spaces and works on both hexagon and 12‑point fasteners, while the solid manufacture ensures consistent fit and long service life when used within its hand‑tool torque limits.
