This is a 7/16in across-flats (AF) 12-point socket designed for use with a 1/2in square drive ratchet, extension or breaker bar. Its primary purpose is to engage and turn 7/16in hexagonal or 12-point fasteners in maintenance, assembly and repair tasks where a 1/2in drive tool is required and a 12-point profile gives easier alignment in confined spaces.

The socket is manufactured from chrome vanadium steel (Cr-V) that has been heat-treated for toughness and durability. The internal head is a 12-point (double-hex) configuration and the drive end is a 1/2in (12.7 mm) square recess compatible with standard 1/2in drive tools. The surface is polished and chrome-plated to provide corrosion resistance and ease of cleaning. This product is produced to industry hand-tool dimensional and performance criteria, meeting recognised DIN/ISO/BS standards for sockets and drives used in professional maintenance and engineering (sockets are for hand tool use; impact-rated sockets are not suitable for this item).

Typical applications include automotive repair and servicing, plant and machinery maintenance, agricultural equipment work and general industrial assembly where imperial fasteners are encountered. The 12-point profile allows engagement on fasteners where clearance or access prevents the use of a 6-point socket, and it is especially useful where quick location and repositioning are required. The chrome vanadium construction and heat treatment deliver high compressive strength and resistance to wear, while the plated finish helps protect against rust in workshop environments.

Key benefits are reliable compatibility with 1/2in drive toolkits, improved access and re-engagement offered by the 12-point head, good corrosion resistance from the plated finish and robust strength from Cr-V steel and heat treatment. The socket is clearly marked with size and DR11580 product code.
