FASThread Nut

Coupling Nut is excited to introduce the FASThread Nut.
It is the first industry grade nut that eliminates problems associated with damaged, rusted or bent thread.

Our newly patented FASThread Nut is designed to succeed where regular threaded connections won’t.

How does FASThread work?

  • It is made up of segments that are able to expand and contract as the nut moves along the rod. Simply push, twist, and tighten.
    • You can slide it on or thread it on
    • Perfect connection every time
    • Increased thread engagement

What are the benefits of FASThread?

  • On damaged bolts, traditional nuts stop or become cross threaded. FASThread technology allows the nut to slide over threads in one pushing motion. No aligning, no threading. It works over damaged, rusty, or bent threads.
    • Saves time and $$
    • Eliminates cross threading
    • No aligning for FAST installation
    • Added strength
    • Removable over damaged threads

FASThread nuts are available in various sizes to meet your application needs.
