What is a Galvanised Coupler Nut?
A Galvanised Coupler Nut (also known as a Threaded Rod Coupler, Coupling Nut, Connecting Nut, or Extension Nut) is a long hexagonal nut designed to join two threaded rods together, creating a continuous threaded connection.
The galvanised finish protects the nut against rust and corrosion, making it suitable for indoor, outdoor, and humid environments.
Whether you're working on commercial buildings, industrial plants, or MEP installations, galvanised coupler nuts provide a reliable fastening solution that stands the test of time.
