JD Brands Back Nut Box Spanner - 1/2" - 3/4" – Heavy-Duty Tap Backnut Tool for Tight Spaces – Dual Ended Sink Basin Plumbing Spanner

• ✅ PIPE SIZE, NOT NUT WIDTH (IMPORTANT) – Marked 1/2″ & 3/4″, which refers to tap pipe size, not the visible nut measurement. The spanner will look larger than expected — this is correct for tap backnuts.
• ✅ FOR TAP BACKNUTS ONLY – Designed specifically for nylon and brass tap backnuts used on basin and sink installations. Not suitable for standard hex nuts or bolts.
• ✅ DUAL-ENDED BOX SPANNER – One tool covers both common tap sizes (1/2″ & 3/4″), reducing the need for multiple tools.
• ✅ TOMMY BAR ACCESS HOLES – Side holes allow use with a tommy bar or screwdriver for added leverage in tight spaces.
• ✅ HEAVY-DUTY CHROME-PLATED STEEL – Durable, corrosion-resistant construction for repeated plumbing and DIY use.

The JD Brands Tap Back Nut Box Spanner is designed specifically for installing and removing tap backnuts behind sinks, basins, and baths where access is restricted. The tool is marked 1/2″ and 3/4″, which refers to the tap pipe size, not the physical width of the nut. As a result, the spanner may appear larger than expected, but this is correct for standard plumbing backnuts. This spanner is suitable for nylon and brass tap backnuts only and is not a general-purpose box spanner. It is not intended for standard bolts, fixings, or cartridge removal. Side holes allow the use of a tommy bar or screwdriver for controlled leverage. Please check before buying: • Confirm your tap uses standard 1/2″ or 3/4″ backnuts • Not suitable for oversized, non-standard, or concealed fixing systems
