When you’re leaning over an engine bay, working behind a guard, or trying to crack a stubborn fastener buried in pipework, standard-length spanners can feel like the wrong tool for the job. The Jefferson Extra Long Double End Ring Spanner Set (7 Piece) is designed to solve that exact problem—giving you the added reach and leverage needed to work efficiently in tight, hard-to-access areas, without compromising on strength.
This set is manufactured from chrome vanadium, chosen for its durability in professional workshop environments. The extra-long profile isn’t just about convenience—it helps you apply torque more smoothly, especially when fasteners are seized or awkwardly positioned. That extra length can reduce effort, improve control, and help make difficult jobs feel more manageable, particularly during repeat maintenance work.
Designed as a metric set, it covers the sizes most commonly used across automotive, plant, agricultural and general engineering work. Each spanner is a double end ring design, offering secure engagement on fastener heads and helping reduce the risk of rounding compared to open-ended alternatives—ideal when you need solid contact and a confident pull.
The set includes seven dual-size spanners, spanning a practical range from smaller fixings through to larger fittings:
8x10mm, 11x13mm, 14x15mm, 16x17mm, 18x19mm, 20x21mm, and 22x24mm. That range makes it a great “go-to” set for day-to-day servicing, repairs, and installation work—whether you’re building out a toolkit or upgrading to longer spanners that reach where others won’t.
This is the ToolUp 13 Deal version of the set (SKU prefix “D-”), using the same core product specification and weight, making it ideal if you’re adding promotional lines to your store while keeping a consistent Jefferson spanner range.
