This is a 13 mm deep socket designed for use with 1/2 inch square drive ratchets, torque wrenches and extension bars. Its primary use is to reach recessed nuts and bolts where a standard shallow socket cannot access the fastener, making it ideal for engine bays, suspension work and general maintenance tasks where additional reach is required.

The socket is manufactured from chrome vanadium (Cr‑V) steel and is heat treated for strength and toughness. It features a polished chrome plated finish to provide corrosion resistance and facilitate cleaning after use. The internal profile is a 6‑point (hex) design to concentrate torque on the flats of fasteners, reducing the risk of rounding, and the square recess accepts a 1/2 in (12.7 mm) drive tool in accordance with common drive interface dimensions used across DIN/ISO/BS hand‑tool practices. As a Draper Tools Group D item (DR27085), it is produced to the dimensional and safety expectations applied to professional hand sockets.

Typical applications include automotive repair (where the depth allows access to head bolts and accessory fasteners), heavy plant and agricultural machinery maintenance, mechanical and electrical installation work, and general industrial MRO tasks. The deep profile suits situations where studs protrude or components obstruct direct access, and the robust Cr‑V construction withstands repeated torqueing in workshop environments.

Key benefits of this 13 mm deep socket are its enhanced reach compared with shallow sockets, improved contact on fastener flats from the 6‑point profile, and the corrosion protection afforded by the chrome finish. Compatibility is high with standard 1/2 in drive ratchets, breakers and extensions, making it a straightforward addition to trade toolkits and professional tool sets.

Duchy Fasteners holds this Draper DR27085 13 mm deep socket in stock for trade and industrial customers, available individually or in bulk packaging to suit workshop and procurement needs. Other metric sizes in the 1/2 in drive deep socket range are also stocked to provide a complete solution for on‑site and workshop applications.
