Product Overview
A coupling nut, such as the Hillman Fasteners model 180213, is an elongated, internally threaded fastener designed to join two externally threaded components, commonly threaded rods or bolts, end-to-end to extend their length. This specific coupling nut features 5/16"-18 UNC-2B internal threads, manufactured to accept corresponding 5/16"-18 UNC-2A external threads. Measuring 1-3/4 inches in length, its hexagonal exterior facilitates installation and removal using standard wrenches. It is constructed from carbon steel and finished with zinc plating, which provides moderate corrosion resistance and acts as a sacrificial anode to protect the underlying steel from rust. Coupling nuts are widely used in various applications including construction, plumbing, HVAC systems, and industrial assemblies.
