This product is a 12mm deep socket with a 1/2in square drive, designed to access recessed or long-stud hexagonal fasteners where a standard shallow socket cannot reach. It is intended for use with 1/2in drive ratchets, torque wrenches and breaker bars to deliver controlled torque in automotive maintenance, plant servicing and general mechanical assembly.

The socket is manufactured from chrome vanadium (Cr-V) steel and is heat-treated and tempered to improve toughness and resistance to deformation under load. The working profile is a 6‑point (hex) internal head to match metric hex nuts and bolts and reduce rounding on heavily torqued fasteners. The drive is a 1/2in square male recess for compatibility with half-inch drive tools, and the product is finished with a bright chrome plating to provide corrosion resistance and ease of cleaning. The socket is produced to meet the common DIN/ISO/BS hand-tool requirements for sockets and fittings and is supplied under Draper Tools Group D (DR27084).

Typical applications include vehicle engine and chassis work, agricultural machinery maintenance, industrial plant repair, and heavy equipment workshops where longer reach and higher torque capacity are required. The deep socket form is particularly useful for bolts with long threads, studs, or where spacers and collars sit above the nut, enabling the user to engage the fastener without removing surrounding components.

Key benefits of this 12mm deep socket include improved access to recessed fasteners, solid hex engagement with reduced fastener damage risk, and good corrosion protection from the chrome finish. The chrome vanadium construction provides the strength needed for professional environments while remaining compatible with standard 1/2in drive toolsets and torque-controlled equipment.

Duchy Fasteners stocks this 12mm deep socket in bulk packs for trade use and supplies a full range of metric deep sockets across common sizes and drive types (1/4in, 3/8in and 1/2in), available as singles or in assorted and bulk packaging to suit workshops and site requirements.
