5 Piece Obstruction Ring Spanner Set Metric

The Siegen 5 Piece Obstruction Ring Spanner Set is a professional metric spanner set designed for working in confined spaces where standard spanners cannot reach. Manufactured from heat-treated Chrome Vanadium steel, this double-ended set provides reliable performance for mechanical and maintenance applications. Each spanner features 12-point WallDrive® bi-hex rings at both ends, delivering improved grip on fasteners whilst reducing the risk of rounding. The obstruction design allows access to nuts and bolts in tight, awkward positions where conventional spanners would be obstructed by surrounding components or structures. The fully polished mirror finish provides corrosion resistance and easy cleaning after use. This five-piece set covers common metric sizes from 8mm through to 22mm, making it suitable for automotive work, machinery maintenance, and general engineering tasks. The spanners are supplied in a practical storage and carry rack for organised workshop storage and transportation between job sites.
