Coupling Nuts
Category : Nuts;
Alias : Long Nuts, Extension Nuts;
Coupling Nuts are long nuts used to couple threaded rods or similar components. Coupling nuts help extend the threaded rod and are so named as an extension nuts. Hex coupling and round coupling nuts are most commonly used types. Other varities include heavy hex coupling nuts. Coupling nut dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These are produced across all material categories and astm specifications.
