The 20mm 6‑point deep socket with a 1/2in drive is a hand socket designed to engage hexagonal fasteners in recessed or hard‑to‑reach locations, where the extra depth allows access to long bolts and studs. It is intended for use with 1/2in (12.7mm) square drive ratchets, T‑handles and torque wrenches for controlled manual tightening and loosening of metric M‑series fasteners.

This Draper Tools Group D item (DR16652) is manufactured from chrome‑vanadium (Cr‑V) steel that has been heat treated for toughness and dimensional stability. The socket is a 6‑point (hex) head form which distributes load on the flats of the bolt, reducing the risk of rounding compared with 12‑point types. The tool features a bright chrome plated finish that resists surface corrosion and eases cleaning. The square drive socket connection is 1/2in, and the socket is produced to DIN/ISO dimensional standards for hand sockets and conforms to relevant British Standards for hand tool safety and interchangeability.

Because this is a hand (non‑impact) deep socket, it is suitable for workshop and maintenance use where ratchet or torque control is required; it is not intended for regular use with pneumatic or electric impact tools. Typical applications include automotive repair and servicing (engine and suspension work), agricultural machinery maintenance, plant and equipment servicing, and general industrial assembly where access to recessed fasteners is needed. The 6‑point profile and deep reach make it especially useful on older hex bolts, studs with protruding threads, and nuts recessed in housings.

Key benefits include the corrosion resistance provided by the chrome finish, the strength and durability of heat‑treated chrome‑vanadium steel, and compatibility with standard 1/2in drive hand tools and torque wrenches. The 6‑point geometry improves load distribution and reduces fastener damage compared with multi‑point sockets.

Duchy Fasteners stocks this style in a comprehensive range of metric sizes and offers individual sockets and set options; our hand socket range typically covers common sizes from around 8mm up to 32mm and is available in single pieces or as part of organised sets and packs.
