Coupling Nuts

You'll never think of specialized hardware until it stands as your only solution, and when that happens, you'll need units quickly.

After all, unusual situations sometimes arise in the midst of a construction or service project. Occasionally, you’ll need an extension nut that can bind together the male ends of two fasteners, and it needs to be a secure connection that eliminates room for potential connection failures.

At FMW Fasteners, we offer a selection of these coupling nuts online, allowing you fast and easy access to the bulk coupling nuts you need.

We Carry High-Quality Coupling Nuts

We are committed to offering only parts that meet the highest standards of quality. That's why you'll find zinc-plated bulk coupling nuts in our selection — extension nuts that will fight against the development of rust and the curse of early deterioration, as it might slow down the process by as much as 10 to 100 percent.

In addition to the added corrosion resistance, these nuts' zinc plating give them added durability when faced with repeated exposure to hot temperatures. Zinc also provides a sleek finish that makes the fastener easier to spot and more aesthetically pleasing.

Overall, our carried line of A563 Grade A hex coupling nuts — also called hex spacers and rod coupling nuts — come in 17 different sizes, offering you comprehensive coverage in a variety of scenarios. It's double chamfered, or beveled, at each end, and it's manufactured using 1010-1018 equivalent steel to meet high marks for durability. These pieces have massive tensile strength, as they can carry a capacity of 60,000 PSI.

As experts in the hardware industry, FMW Fasteners employs a customer service team that will assist you in selecting the right coupling cut. Their specifications may shift as the size changes, and we'll help to identify how that might affect the fit for your job.

Uses for Coupling Fasteners

Coupling fasteners will join together two externally threaded objects that measure at the same size and pitch. Joining two rods to extend their length as part of a construction project is a typical scenario for these fasteners, but you can connect different parts, as well.

Bring together a hanging bolt and a threaded rod, for example. Coupling nuts do function as spacers and standoffs, depending on the task. They generally work well in plumbing, electrical work, building construction and more.

You could even create a jury-rigged driving tool for hanging bolts by cutting off the head of a hex socket shoulder screw and then threading the body into a coupling nut. Finally, insert the shoulder into a drill and thread the hanging bolt into the opposite end of the nut.
