Coupling Nuts

Coupling nuts are commonly used in industrial applications to connect two threaded fasteners together. These cylindrical nuts feature internal threading that matches the external threading of the fasteners they are intended to join. Coupling nuts are often used in applications requiring longer lengths of threaded rods or pipes or where a joint needs to be adjustable or removable. They are commonly used in industrial applications, including construction, mechanical engineering, and plumbing, and are available in various sizes and materials.
