Coupling Nuts

Coupling nuts (also known as a rod coupling, rod coupling nut, coupler nut, or extension nut), is a threaded fastener for joining two male threads, most commonly threaded rods. The outside surface of the coupling nut is usually a hex shape to allow for wrench tightening. Reducing coupling nuts are a variant design that allows the joining of two rods of differing thread sizes.

Trust AFT with supplying your metric and SAE coupling nuts. We provide a wide range of sizes and finishes including hot dipped galvanized, plain and zinc. Please contact us today if you can’t find the exact product or size needed as we have many products not listed on our website.
