The Siegen 12 Piece Colour Coded Ratchet Combination Spanner Set is a professional metric spanner set featuring Chrome Vanadium steel construction for durability and reliability. Each spanner combines an open-end and 12-point WallDrive® ring design, with the ring end incorporating a 72-tooth ratchet mechanism that requires just 5º rotation to pick up the next tooth. This fine-tooth ratchet action makes the set ideal for working in confined spaces where a full swing isn't possible, allowing you to keep the spanner on the fastener whilst working in tight engine bays, behind pipework, or in compact machinery assemblies.
The spanners are hardened and tempered for strength, then chrome plated for corrosion resistance and finished with a colour-coded mirror polish that helps with quick size identification in your tool bag or on site. The set covers the most commonly used metric sizes from 8mm through to 19mm, spanning twelve sizes in total to suit a wide range of automotive, mechanical and general maintenance applications. All spanners are supplied in a practical storage and carry rack that keeps them organised and protected between jobs.
