Coupling Nut is a long, internally threaded fastener designed to join two threaded rods, studs, or bolts together. Its extended length provides sufficient thread engagement on both sides, creating a strong and continuous threaded connection. The external hexagonal shape allows easy installation and tightening using standard tools.
Coupling Nuts are widely used in construction, structural applications, machinery, electrical installations, solar mounting systems, maintenance work, and general engineering projects. They are particularly useful when extending the length of threaded rods or connecting two threaded components securely.
Coupling Nuts can be manufactured from carbon steel, stainless steel, alloy steel, and other specified materials according to application requirements. Various surface finishes, including plain, zinc-plated, and hot-dip galvanized, can be provided for improved durability and corrosion resistance.
