The sealey ak7979 is a 4 in 1 reversible ratchet ring spanner designed to provide versatile fastening solutions across four different metric sizes. This innovative spanner combines 10mm, 13mm, 17mm and 19mm sizes in a single 200mm tool, eliminating the need to carry multiple spanners for common fastener applications. Manufactured from chrome vanadium steel and hardened and tempered for durability, this ratchet spanner features a fully polished black chrome finish that resists corrosion whilst providing a professional appearance. The 72 tooth ratchet mechanism requires only 5° rotation to pick up the next tooth, making it ideal for working in confined spaces where conventional spanners cannot achieve a full swing arc. This multi size spanner is particularly suited to automotive work, maintenance tasks and assembly applications where space constraints limit tool movement. The reversible ratchet action allows for quick directional changes without removing the spanner from the fastener. Backed by a lifetime guarantee, the ak7979 offers a practical solution for tradespeople and mechanics who value efficiency and tool consolidation.
