This product is a 15 mm, 6-point socket with a 3/8" square drive, designed to fit standard metric hexagon nuts and bolt heads for general workshop and maintenance use. Its primary use is as a medium-duty hand tool interface between a 3/8" drive ratchet, breaker bar or torque wrench and 15 mm fasteners, providing a positive seating on hex heads for assembly, servicing and repair tasks.

The socket is manufactured from chrome vanadium steel (Cr-V) and is heat-treated for toughness and wear resistance. The external finish is bright chrome plating to resist corrosion and make cleaning straightforward; the internal bore is machined to a 6-point (hex) profile that conforms to recognised metric hexagon dimensions so it will seat correctly on ISO/DIN hex fasteners. The drive connection is a 3/8" (9.5 mm) square recess compatible with industry-standard 3/8" drive tools. Thread type is not applicable for this socket, as it connects to tools by square drive engagement rather than a threaded coupling.

Typical applications include automotive maintenance and repair, light engineering, plant maintenance, HVAC servicing and agricultural machinery work where medium torque is required. The 6-point configuration reduces the risk of rounding hex heads compared with a 12-point design, making it preferable for use on worn or high-torque fasteners. The socket is also suitable for use in confined spaces where precise engagement is needed and with accessories such as extensions and universal joints for awkward angles.

Key benefits of this 15 mm 6-point socket are its material strength from chrome vanadium construction, the corrosion resistance offered by chrome plating, and the broad compatibility with 3/8" drive ratchets and torque tools. The 6-point profile provides solid contact on flat sides of fasteners, improving torque transfer and reducing damage to heads. It is suitable for repeated workshop use and maintenance schedules where reliable fit and durability are required.

Duchy Fasteners stocks this socket as a single item and as part of metric socket sets; our fastener range typically covers metric sizes from small to large (commonly 4 mm up to 24 mm) and is available in single-piece packs and multi-socket sets to suit workshop and professional requirements.
