The Draper 11 Piece Combination Spanner Set Imperial delivers professional-grade hand tools for working with imperial fasteners across automotive, engineering and machinery maintenance applications. Each spanner is forged from chrome vanadium steel, hardened and tempered to provide the strength and durability required for demanding workshop environments. The chrome plating offers excellent corrosion resistance, ensuring long-term performance even in challenging conditions. Draper's HI-TORQ® ring end design maximises contact with fastener faces, reducing the risk of rounding whilst delivering superior torque transfer. Both the ring and open ends are offset at 15°, providing improved access in confined spaces and allowing clearance for hands when working close to obstructions. The set covers commonly used imperial sizes from 1/4" through to 7/8" AF, making it ideal for tradespeople working on American vehicles, classic cars, imported machinery or equipment manufactured to imperial standards. The included Tetron divided wallet keeps spanners organised and protected during storage and transportation, with individual pockets preventing tools from rubbing together. A tie cord secures the wallet closed, making this set practical for mobile mechanics, plant engineers and workshop professionals.
