This is an 11 mm ratcheting combination spanner from Draper Tools Group D (DR31008), designed to loosen and tighten 11 mm metric hex nuts and bolts where speed and access are important. The tool combines a slim open-end and a ratcheting ring end so you can grip fasteners in tight locations and operate continuously without removing and refitting the spanner.

Manufactured from chrome vanadium steel (Cr-V) and heat-treated for improved tensile and torsional strength, the spanner features a polished chrome finish that resists surface corrosion and eases cleaning. The open-end conforms to recognised spanner dimensions while the ring end houses a fine-tooth ratchet mechanism (commonly a 72-tooth design) to allow a small swing angle for use in confined spaces. As a hand tool, thread type is not applicable. The product is produced to align with standard DIN/ISO/BS hand tool dimensional and performance expectations for spanners, and is compatible with typical metric fastener tolerances found in engineering and maintenance work.

Typical applications include automotive and motorcycle maintenance, industrial equipment servicing, plant maintenance, assembly-line work and HVAC installations where an 11 mm fastener is used. The ratcheting ring end accelerates repetitive tasks and reduces operator fatigue compared with non-ratcheting combination spanners; the slim profile of the open end also helps access fasteners where clearance is limited.

Key benefits include improved efficiency from the ratcheting action, reliable strength from Cr-V heat treatment, and moderate corrosion resistance from the chrome finish. The spanner’s metric sizing makes it directly compatible with DIN/ISO metric hexagon nuts and bolts, and it can often replace the need for a socket and ratchet in many confined applications.

Duchy Fasteners stocks this Draper ratcheting spanner individually (DR31008) and as part of Draper Group D tool sets. We carry a comprehensive metric range from small sizes up to larger spanners, available single-piece, in multi-piece sets and in assorted economy packs to suit workshop and trade requirements.
