The 22mm ratcheting combination spanner is a hand tool designed for rapid fastening and unfastening of 22 millimetre metric hexagon nuts and bolts where a slim open jaw and a ratcheting box end are both required. Its primary use is to give quick, continuous movement on fasteners in confined or awkward positions without the need to remove and reposition the tool after each turn.

This spanner is manufactured from chrome vanadium (Cr‑V) steel that has been heat treated for strength and toughness. The open end provides a precise 22mm jaw for gripping flats, while the opposite end houses a 12‑point ratcheting ring. The ratchet mechanism is a fine‑tooth design (72‑tooth), giving an approximate 5° swing arc for use in tight access situations and enabling reversible operation to tighten or loosen fasteners without flipping the tool. The finished part is polished and chrome plated to resist corrosion and to aid cleaning after use.

The tool’s dimensions and tolerances are produced to meet recognised combination spanner standards and conform with DIN, ISO and BS dimensional requirements for metric spanners, ensuring correct fit on ISO metric fasteners. It is suited to standard ISO metric threads and typical hexagon nut geometries encountered across industry.

Typical applications include automotive repair and maintenance, plant and machinery assembly, mechanical engineering, HVAC and plumbing installations, and agricultural equipment servicing. The slim open end allows entry where thicker jaws cannot reach, while the ratcheting box end speeds repetitive tasks and reduces operator fatigue on assembly lines or during field service calls.

Key benefits of this 22mm ratcheting combination spanner are its material strength from Cr‑V construction and heat treatment, the corrosion resistance provided by the polished chrome finish, and compatibility with standard metric nuts and bolts thanks to adherence to DIN/ISO/BS dimensions. The reversible ratchet and narrow swing angle make it particularly effective in restricted spaces.

Duchy Fasteners stocks this spanner individually and in mixed spanner sets; our range typically covers metric sizes from 6mm up to 32mm and is available in single packs and boxed multi‑packs for workshop or site use.
