Quickly and easily fix inch, metric, & pipe

Our heart is to help people from different industries to save their time and money in all of their repair and restoration projects.

Our solutions come from 60+ years of family-owned machine shop and repair business. The design of our tool is simple, so simple that it will make you wonder how it works.

Simple to Use

  1. Use light pressure
  2. Start in a good thread
  3. Move to damaged thread
  4. Repeat as needed

The “V” angle is the same “V” for outside threads as it is on the inside threads. One goes around a shaft (outside), the other around a hole (inside). Rotary thread restoration uses a singlepoint to restore the thread. The tool’s designed to restore the continuous “V” and help you finish a project without a fuss.

One tool for different projects

No tool in the thread industry delivers a satisfying repair as this tool. It’s not easy to develop something so easy and so truly effective at what it does. We filed patents and began the journey. We made modifications and improved the design so you can restore any threads for any project in the most efficient way. Rotary Thread can be used for every aspect of work. Whether for DIY projects, automotive restoration, home improvement, technical projects, industrial projects, and even farm and ranch projects too!
