Coupling Nuts: Threaded Rod Couplers
Coupling nuts, often called extension nuts or threaded rod couplers, are threaded fasteners used to connect two externally threaded rod shafts. The coupling nut has internal threading that allows the external shaft to be inserted from both sides, effectively joining the two threaded pieces and allowing for custom length connections or adjustments during installation. These hex coupling nuts are hexagon-shaped and installed with standard tools, such as wrenches. They are vital for applications requiring a longer thread connection to extend the assembly’s length.
We also offer reducing coupling nuts, which are specialized coupler nuts that feature different thread size requirements on each end. These are ideal for repair and maintenance applications where joining dissimilar rod diameters is necessary. Explore our full range of nuts and general fasteners.
