The Faithfull 3 Piece Monobloc Box Spanner Set provides a complete solution for installing and servicing monobloc tap fittings. This set includes three double-ended box spanners in the most commonly required sizes, along with a tommy bar for added leverage when working with tight backnuts. Each double-ended spanner is specifically designed for accessing monobloc tap backnuts in confined spaces under sinks and basins. The set covers six essential sizes across three spanners: 8 x 9mm, 10 x 11mm, and 12 x 13mm, ensuring compatibility with the majority of monobloc tap installations encountered by plumbers and bathroom fitters. The included tommy bar slots through the spanner to provide the extra torque needed for securing or removing stubborn backnuts. This makes the set ideal for tap installations, bathroom refurbishments, and maintenance work where standard spanners cannot reach or fit around tap fittings.
