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.
