This item is an 8 mm, 6-point deep socket with a 3/8" drive, designed to fit metric hex nuts and bolts where extra reach is required. Its primary use is to allow a 3/8" ratchet or extension bar to access recessed or long-stud fasteners safely and accurately during assembly, maintenance or repair tasks.

The socket is manufactured from chrome vanadium steel (Cr-V), heat-treated and tempered to provide torsional strength and wear resistance. It is finished with a bright chrome plating to give good corrosion protection and an easy-to-clean surface. The 3/8" drive corresponds to a 9.5 mm square recess with spring-ball retention for secure attachment to ratchets and adapters. The internal profile is a 6-point (hex) form, matching hexagonal fasteners and reducing the risk of rounding compared with 12-point designs when used with the correct size. This socket is intended for hand-tool use; it is not an impact socket and should not be used with pneumatic or electric impact wrenches.

The socket is produced to conventional hand-tool dimensional profiles in line with recognised DIN/ISO/BS practice for shallow and deep 6-point sockets, ensuring interchangeability with other tools and correct fit on ISO metric fasteners. Typical applications include automotive work (engine, brake and suspension maintenance), plant and machinery servicing, electrical and mechanical assembly, plumbing and HVAC tasks, and general industrial maintenance where metric hex fasteners are common.

Key benefits of this 8 mm 6pt deep socket include the improved engagement and reduced rounding risk offered by the 6-point profile, the ability to reach nuts on long studs or in recessed positions due to the deep socket body, corrosion resistance from the chrome finish, and the strength and durability provided by heat-treated chrome vanadium steel. It is compatible with all standard 3/8" drive ratchets, torque wrenches and extension bars, making it a versatile addition to a tool kit.
