3PC Mono-Bloc Tap Back Nut Spanner Set

This 3PC Mono-Bloc Tap Back Nut Spanner Set is an essential kit for any plumber or bathroom installer. Designed specifically for mono-bloc tap fittings, these spanners allow for quick and secure tightening or loosening of back nuts in tight and hard-to-reach spaces — such as under basins and sinks. Each spanner is dual-ended, offering a range of sizes: 8–9mm, 10–11mm, and 12–13mm. The open-ended design allows for easy positioning over tap tails, while the slim profile fits into narrow gaps with ease. Perfect for both professional and DIY installations, this set saves time and hassle when working on taps in confined areas.
