Coupling Nuts are elongated nuts designed to connect two threaded components, such as rods or bolts, effectively extending their length. Often referred to as extension nuts, they serve a vital role in applications requiring additional reach or alignment. The most common types include hex coupling nuts and round coupling nuts, with heavy hex coupling nuts available for more demanding structural applications.

These nuts are manufactured in both metric and imperial dimensions, supporting UNC, UNF, UN, and ISO metric thread standards. They are available in a wide range of materials, grades, and ASTM specifications to suit diverse industrial needs.
