Coupling nuts are cylindrical fasteners with internal threads on both ends, designed to connect two threaded rods or studs. Typically hexagonal in shape, they facilitate secure joining of threaded components by extending the length of the connection. These nuts are commonly used in construction, manufacturing, and structural applications, providing versatility in creating adjustable connections or extending hardware lengths. The internal threads ensure compatibility with external threads of rods or studs, promoting ease of assembly and disassembly. Made from various materials, coupling nuts offer durability and strength, enhancing stability in diverse mechanical and structural configurations.
