Coupling Nuts
Coupling nuts, or hex coupling nuts, are long, internally threaded fasteners that connect metal components. While similar in design to heavy hex nuts, these fasteners are used to “couple” or join two externally threaded rods and form durable connections. Coupling nuts can be threaded onto each rod, firmly securing the components into one functional element. These nuts are available in an assortment of materials and sizes for unique applications across numerous industries.

Hex Coupling Nut Features
Coupling nuts, also known as extension nuts, connect and extend rods for various applications. They can thread any externally threaded rod of the same dimensions and threading, including solid rods, bolts, or piping. Their hexagonal external shape allows them to be installed or removed quickly with installation tools such as a wrench or socket set. Rod couplings provide easy and strong solutions for metal fastener connections.Materials & Finishes for Rod Couplings
With a variety of materials and finish options, coupling nuts are suitable for use in a range of applications across multiple industries. The various steel compositions of rod couplings from Trio Fasteners contain different percent levels of carbon, each offering unique benefits.Low-carbon steel is highly machinable and offers excellent weldability and flexibility. Medium-carbon materials include T-316 stainless steel, 18-8 stainless steel, and A194 Grade 2H. These steels have an increased heat response and strength, allowing for more versatile applications. High-carbon materials include Grade 5 and Grade 8 steels, which feature high hardness, wear resistance, and excellent edge retention, making these metals well-suited for high-stress or harsh environments.
Finishes for our coupling nuts include zinc, plain, and hot-dipped galvanized (HDG). These cost-effective finishes offer numerous benefits, including increased corrosion resistance, longevity, durability, and weldability.
