This is a 25 mm, 6-point metric socket designed for hand use with a 1/2" square drive ratchet or breaker bar. Its primary use is to engage hex-headed bolts and nuts where a robust, positive six-face contact is required, making it ideal for applying higher torque without rounding fastener corners.

The socket is manufactured from chrome vanadium (Cr-V) steel and is heat treated to provide enhanced tensile strength and durability; typical hardness after treatment is in the mid to high range required for hand sockets. The external finish is bright chrome plating to resist corrosion and simplify cleaning. The socket features a 6-point (hex) internal profile and a 1/2" square drive recess, compatible with standard 1/2" drive ratchets, torque wrenches and extensions. Designed to meet common industry specifications for hand sockets, it is produced to recognised DIN and ISO socket standards (for example DIN 3124 / ISO 1174) and conforms to typical UK BS tolerances for fit and finish.

This 25 mm 6pt socket is commonly used in automotive maintenance, commercial vehicle repair, construction plant maintenance, agricultural machinery servicing and general engineering workshops. The 6-point configuration makes it particularly suitable where stubborn or slightly rounded fasteners are encountered and where a tight, non-slip engagement is essential. It is intended for hand-tool use and should not be used with impact tools unless specifically marked as impact-rated.

Key benefits include the corrosion resistance of the chrome finish, the strength and wear resistance afforded by the chrome vanadium material and heat treatment, and wide compatibility with 1/2" drive toolsets and accessories. The 6-point geometry reduces the risk of fastener damage compared to 12-point sockets when applying heavy torque.

Duchy Fasteners stocks an extensive range of metric sockets in single and set formats; this item is available individually and as part of 1/2" drive socket sets. Our metric socket range covers popular sizes to suit trade and industrial requirements, with multiple pack options for workshop use.
