The Siegen 6 Piece Flexible Ring Spanner Set is a professional metric spanner set engineered for tight-access applications where standard spanners cannot reach. Manufactured from durable Chrome Vanadium steel, this double-ended ratchet spanner set features an innovative flexible ring head design that allows tradespeople to work around obstructions and awkward angles. Each spanner incorporates a precision 72-tooth ratchet ring and gear mechanism requiring only 5° of rotation to engage the next tooth, making it particularly effective in confined spaces where a full swing is impossible. The set covers essential metric sizes from 8mm through to 19mm across six double-ended spanners: 8 x 9mm, 10 x 11mm, 12 x 13mm, 14 x 15mm, 16 x 17mm, and 18 x 19mm. Ideal for automotive mechanics, plant maintenance engineers, and general engineering applications, this spanner set excels where access is restricted and flexibility is crucial. The set is supplied with a storage rack to keep spanners organised
