1/4"-20 Stainless steel helical inserts are used to reinforce and repair tapped holes in soft metals.
- Feature strong, corrosion resistant internal threads
- Engineered to withstand temperatures up to 800 degrees Fahrenheit
- The diameter of a helical insert will be larger than the tapped hole (before install)
- Once properly installed the insert diameter reduces allowing the helical insert to thread the hole
After installation, E-Z Lok coil inserts will stay firmly in place as the radial pressure of the spring releases.
Stainless Steel Helical Threaded Inserts are ideal for applications requiring additional corrosion resistance, as well as automotive, food, beverage, and other clean-critical applications.
