Hex Coupling Nut Threaded Connector For Rod Connection Aluminum Profile Construction Hardware

Hex Coupling Nut Threaded Connector For Rod Connection Aluminum Profile Construction Hardware

Our durable Hex Coupling Nut Threaded Connector For Rod Connection Aluminum Profile Construction Hardware from Qimao Metal Manufacturer looks like a longer version of a standard hex nut, but both ends are threaded. You screw one rod into one side, another rod into the other side, and it pulls them together into a single, longer connection. We originally started making these for customers who build aluminum profile structures – machine guards, workbenches, display racks, even solar panel frames. Over time, the same part ended up in construction hardware, curtain walls, and industrial rod linkage systems.
