The Sealey 23 Piece Combination Spanner Set delivers comprehensive coverage for professional mechanics and engineers working across metric and imperial applications. This cold stamped Chrome Vanadium steel spanner set features a slim profile design that provides improved access in confined spaces whilst maintaining the strength required for demanding workshop tasks. Each spanner combines an open-end with a 12-point WallDrive® ring configuration, offering versatility for different fastening situations. The WallDrive® technology engages the flat sides of fasteners rather than the corners, reducing the risk of rounding and providing superior grip on worn or damaged fixings. The satin polished finish enhances corrosion resistance, ensuring long-term durability in challenging workshop environments. The set includes twelve metric sizes from 8mm through to 19mm, plus eleven imperial sizes ranging from 1/4" to 7/8", making it ideal for automotive repair, maintenance work, and mechanical assembly tasks where both measurement systems are encountered. All spanners are organised in a practical 25mm EVA storage tray that protects the tools and maintains workshop organisation. The set is backed by a lifetime guarantee for professional peace of mind.
