Coupling Nuts are defined by their elongated hexagonal shape and are used to connect two pieces of threaded material at opposite ends. Coupling nuts are commonly used in mechanical and industrial applications to connect lengths of threaded rod for the purposes of creating a longer threaded piece. These coupling nuts feature two inspection holes so that the threaded rod connection can be checked visually.

Looking for more information on nuts, bolts and washers? Check out our guide on fasteners in the product documents section.

  • FOR INDUSTRIAL APPLICATIONS: Used to make up long rod assemblies from shorter lengths of rods
  • SIMILAR FUNCTION TO HEX NUTS: Coupling nuts are elongated hex nuts designed to connect rather than finish
  • EASILY INSPECT CONNECTIONS: Parts feature punched holes for visual inspection of the interior threaded fasteners
  • PART OF A COMPLETE FASTENING SOLUTION: Use with bolts, threaded rods, or washers of the same thread size and finish
  • CORROSION-RESISTANT FINISH: Zinc plating offers moderate protection against rust and corrosion
