The sealey 8 piece offset double ring spanner set is a professional grade hand tool set designed for accessing fasteners in confined spaces. Manufactured from heat treated and hardened chrome vanadium steel, this spanner set delivers the strength and durability required for daily workshop and site use. Each spanner features deep offset walldrive® rings that provide superior grip on fastener faces rather than corners, reducing the risk of rounding. The offset design allows better clearance when working around obstructions, making these spanners ideal for automotive maintenance, machinery repair, and general engineering applications. The satin polished finish offers resistance to corrosion, ensuring long term performance in demanding environments. This comprehensive set covers common metric sizes from 6mm through to 22mm, with each spanner offering two sizes for maximum versatility. The double ended configuration provides excellent value, giving you 16 working sizes across 8 tools. A storage pouch is included to keep your spanners organised and protected, whether in the workshop or on site. Backed by a lifetime guarantee, this set represents a reliable addition to any professional tool kit.
