The sealey 4 in 1 reversible flexible head ratchet ring spanner is a versatile ratchet spanner designed to reduce the number of tools required in your toolkit. Manufactured from hardened and tempered chrome vanadium steel with a fully polished micro satin finish, this professional grade spanner delivers durability and corrosion resistance for demanding trade applications. The innovative four size ring design provides 10mm, 13mm, 17mm and 19mm coverage on a single spanner, making it ideal for mechanics, plant fitters and general engineering work where multiple fastener sizes are encountered. The 100 tooth ratchet mechanism requires only 3.6° rotation to pick up the next tooth, allowing you to work effectively in confined spaces where conventional spanners would require excessive swing arc. The flexible head design enhances accessibility in awkward positions, whilst the reversible ratchet action enables both tightening and loosening without removing the spanner from the fastener. At 235mm in length, this spanner offers a practical balance between reach and manoeuvrability, with a lightweight 0.27kg construction that won't add unnecessary weight to your toolbox.
