Aluminum Coupling Nuts

Rod Coupling Nuts in 6061-T Aluminum Alloy


  • Join two male threads
  • Commonly used with threaded rod
  • Make longer rod assemblies from shorter lengths
  • Also known as Extension Nuts
  • Resistant to Atmospheric Corrosion
  • Significantly Lighter than Other Alloys
  • 6061-T6 Aluminum Alloy
  • High Strength-To-Weight Ratio
  • UNC Coarse Thread Sizes

An Aluminum Coupling Nut, also known as an extension nut, is corrosion resistant, lightweight, and non magnetic. As a metal, aluminum is valued for its high strength-to-weight ratio making it a common fastener material in the automotive, aerospace, and general machinery industries.

Important: We recommend not mixing metals; aluminum fasteners should be used with aluminum fasteners. For more information, please read our article on the subject HERE.
