This is a 1/4" square drive, 6‑point deep socket in 7 mm size, designed to access and turn hexagonal metric fasteners where recessed or hard‑to‑reach nuts and bolts are present. Its primary use is for low‑to‑medium torque applications on small fasteners commonly found in mechanical assembly, maintenance and service work where a shallow socket will not reach.

The socket is manufactured from chrome‑vanadium (Cr‑V) steel and is heat‑treated and hardened to provide wear resistance and dimensional stability. The exterior is chrome plated and polished to resist corrosion and simplify cleaning. The tool conforms to common DIN/ISO/BS tolerances for hand sockets and is compatible with industry‑standard 1/4" (6.35 mm) square drive tools. As a 6‑point design, the socket fully engages the flat faces of hex fasteners rather than the corners, reducing the risk of rounding and improving torque transfer compared with 12‑point alternatives. The deep profile gives extra reach for studs and recessed fasteners; there is no threaded connection—engagement is via the standard 1/4" drive recess.

Typical applications include precision mechanical work, light automotive and motorcycle maintenance, bicycle repair, electronics enclosures, HVAC servicing and general workshop assembly where metric 7 mm fasteners are used. The 1/4" drive size makes the socket especially suitable for use with 1/4" ratchets, spinner handles, extensions and compact torque wrenches used in production and maintenance environments.

Key benefits are reliable corrosion resistance from the chrome finish, consistent strength and toughness from the Cr‑V material and heat treatment, and improved fastener protection thanks to the 6‑point profile. Compatibility with standard 1/4" accessories ensures straightforward interchangeability in existing toolkits and on-site tooling setups.
