The Draper 4 Piece Ring Obstruction Spanner Set is a professional metric spanner set designed for working in confined spaces where standard spanners cannot reach. Forged from chrome vanadium steel, these obstruction spanners feature Draper's HI-TORQ® ring ends for superior grip and torque transfer on fasteners. Each spanner is hardened and tempered for durability, then finished with a satin chrome plating that provides corrosion protection in demanding workshop and site environments. The offset ring design allows access to recessed nuts and bolts in tight spaces, making this set ideal for automotive work, plumbing installations, and machinery maintenance where access is restricted. The set covers commonly used metric sizes including 11 x 13mm, 13 x 15mm, 14 x 17mm, and 19 x 22mm, providing double-ended versatility for a range of fastener applications. Supplied in a convenient storage wallet, the spanners stay organised and protected between jobs.
