The Siegen S01156 is a comprehensive 17-piece metric ratchet spanner set engineered for professional mechanics and engineers working in confined spaces. Manufactured from durable chrome vanadium steel, this combination spanner set delivers the strength and corrosion resistance required for demanding workshop environments. The 72-tooth ratchet mechanism is the standout feature of this set, requiring just 5° rotation to engage the next tooth. This fine-tooth design proves invaluable when working in restricted areas where conventional spanners lack the swing arc needed for efficient operation. Each spanner combines an open-ended spanner at one end with a ratcheting ring at the other, offering versatility for different fastening applications. The set provides extensive metric coverage from 8mm through to 32mm, including commonly used sizes: 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 22, 24, 27, 30, and 32mm.
