Secure, leak-resistant fastening, with standard 1/2" BSP female threads

G1/2-inch female threads match standard 1/2" BSP fittings commonly used on basin taps and mixers, allowing straightforward hand or spanner tightening. The precise outer and inner diameters help ensure a snug mechanical fit against the basin surface.

A secure connection reduces wobble and helps prevent leaks during normal use, making fittings more reliable over time.

Corrosion and heat resistance, with high-quality ABS plastic

ABS plastic construction resists corrosion and tolerates bathroom temperatures and humidity, avoiding common rusting or seizing issues associated with some metal fasteners. The flanged form spreads load across the basin to maintain integrity.

Long-term performance in wet environments is improved, so fittings remain functional and presentable without frequent replacement.

Practical spare supply, with a convenient six-piece pack

Supplied as six flanged back nuts, ready for multiple installations or to keep as spare parts on the van or at home. Standard sizing means the same pack can cover several common tap fittings.

Tradespeople and homeowners can complete several jobs or replace lost parts without sourcing single items, saving time and avoiding interruptions.
