Coupling Coil Nuts

Coupling nuts are normally used to connect two pieces of threaded rod or pipe together. Coupling coil nuts are most likely manufactured in low carbon steel plain or zinc plated, but can be custom made to your specifications.
They can be installed by screwing onto exposed thread by hand and tightening with a wrench.
