Thees Hillman 3/8 in.-16 Zinc 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. Zinc plating offers moderate protection against rust and corrosion.

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
  • 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
  • STRONG, STURDY, RELIABLE: Made of high-quality steel

Speical project.

I was making a special device and need a coupling to join 2 rods. It worked for me but my design was not working. Also this was the only store in town to have one this size.

Yes, I recommend this product.
