The sealey stubby offset double ring spanner is a compact metric spanner designed for accessing fasteners in confined spaces. Manufactured from drop forged chrome vanadium steel, this professional grade tool features a hardened and tempered construction with a fully polished mirror finish for long lasting durability. The stubby, compact configuration makes this spanner ideal for tight workspaces where standard length spanners cannot reach. The 45° offset walldrive® rings provide improved access and enhanced grip on fasteners, reducing the risk of rounding corners whilst delivering maximum torque transfer in restricted areas. This versatile double ended spanner combines two of the most commonly used fastener sizes – 10mm and 13mm – making it an essential addition to any professional toolkit. Particularly popular with rowers as a rigger jigger, it undoes every nut in a european rowing boat, with the 10mm end for riggers and the 13mm end for top nuts, though its applications extend across general mechanical, automotive, and maintenance work.
