Siegen 5 Piece S Type Ring Spanner Set Metric

The Siegen 5 Piece S Type Ring Spanner Set is a professional-grade metric spanner set designed for reliable fastening and loosening applications across automotive, mechanical and general maintenance tasks. Manufactured from chrome vanadium steel, these spanners feature heat treatment for enhanced strength and durability, finished with a fully polished mirror finish that resists corrosion whilst providing a professional appearance. The distinctive S-profile design offers improved access in confined spaces, making these spanners particularly useful when working around obstructions or in tight engine bays. Each spanner features WallDrive® bi-hex ring profiles that grip the flat sides of fasteners rather than the corners, reducing the risk of rounding and allowing greater torque application. The double-ended configuration provides ten commonly used metric sizes from 10mm through to 19mm, covering the majority of fastener sizes encountered in routine mechanical work. The set is supplied in a practical storage and hanging pouch for organised tool storage and quick size identification on site.
