This is a 15mm 12-point socket with a 3/8" square drive, designed for use with 3/8" (9.5mm) ratchets, extensions and compatible hand tools. Its primary use is to engage and turn 12-point and 6-point fasteners in general mechanical work where a compact engagement angle and rapid indexing are required, especially in confined spaces where frequent re-positioning is necessary.

The socket is manufactured from chrome vanadium steel (Cr-V) and is heat treated to develop high strength and toughness suitable for repeated workshop use. The external finish is a bright chrome plate that provides good corrosion resistance and allows easy cleaning of oil and grease. The socket features a 12-point internal profile and a 3/8" square drive recess; its dimensions conform to common DIN/ISO dimensional profiles for hand sockets, ensuring interchangeability with standard ratchets and accessory tools used in industry.

Typical applications include automotive repair and maintenance, light engineering, plant maintenance, appliance servicing and general workshop use. The 12-point profile makes the socket particularly useful where fast engagement is needed on fine-pitch or shallow-headed fasteners and in situations where access is limited and a smaller swing is advantageous. It is also suitable for use on many 6-point fasteners, though care should be taken with heavily corroded or rounded heads to avoid further damage.

Key benefits of this socket are its corrosion-resistant chrome finish, the strength and fatigue resistance of heat-treated chrome vanadium steel, and the common 3/8" drive compatibility that makes it a versatile addition to hand tool sets. The 12-point geometry provides multiple contact positions for quicker alignment and reduced working angle compared with some alternatives.
