DIC Fasteners has been supplying Coupling Nuts, hex-shaped nuts which are usually used to join the externally threaded fasteners together. We carry Coupling Nuts in many different sizes, materials, and dimensions.
A Coupling nut is a metal fastener that is designed to secure the objects together by screwing these nuts into the outer side of another part. Usually, coupling nuts may be made of any material, but the most common coupling nuts are metal due to their durability and the variety of applications in which they may be used.
These metal coupling nuts can be made out of stainless steel, carbon steel, brass, or aluminum. As these nuts help in extending the threaded rod and so they are also named extension nuts. The most common type of these nuts includes hex coupling and round coupling. Hex coupling nuts are useful to attach two parts of a threaded material on the other hand Round coupling nuts have a smooth rounded body for a finished look. Coupling nuts are unique in style and are used in construction, Automobile, and engineering nuts.
