This is a 23 mm impact socket with a 3/4 inch (3/4dr) square drive, designed for removing and tightening nuts and bolts under high torque with pneumatic or electric impact wrenches. Its primary use is for heavy-duty fastening tasks where standard chrome sockets would fail: wheel nuts on commercial vehicles, construction plant maintenance, agricultural machinery and other industrial applications that require repeated high-torque impacts.

The socket is manufactured from chrome‑molybdenum (Cr‑Mo) impact steel and is quenched and tempered to withstand shock loading from impact tools. It features a 6‑point internal hex profile to give positive contact on the flats of fasteners and reduce rounding. The external finish is a matt black phosphate/oxide coating to resist corrosion and minimise glare. The socket accepts a 3/4" square drive and is compatible with standard detent pins or retaining rings on impact tools; it has no threaded connection. Machining and dimensions are produced to industry socket dimensional standards (per DIN/ISO socket profiles and comparable BS tolerances) to ensure interchangeability with other 3/4" drive tools.

Typical industries for this 23 mm 3/4dr impact socket include commercial vehicle workshops, plant hire and maintenance, civil engineering, utilities and heavy fabrication. It is particularly useful where high breakaway torque is required, for example removing seized wheel nuts, large fasteners on agricultural implements or assembly/disassembly of heavy machinery. The Cr‑Mo construction gives superior toughness under repeated impact, while the 6‑point profile concentrates load on the flats to reduce fastener damage compared with 12‑point designs at high torque.

Key benefits include resistance to cracking and chipping under impact conditions, good corrosion protection from the black phosphate finish, and compatibility with all 3/4" drive impact wrenches, torque multipliers and breaker bars. Duchy Fasteners stocks this Draper Tools Group D 23 mm impact socket individually and as part of Draper impact socket sets, with a wider range of metric sizes typically available across single pieces and boxed multi‑packs to suit workshop requirements.
