Stainless Steel E-Z Coil Helical Threaded Inserts

Internal Thread Size: 1/4"-28

Helical Inserts, also known as Coil Threaded Inserts or Wire Threaded Inserts are used to reinforce and repair tapped holes in soft metals. E-Z Lok Helical Inserts feature strong, corrosion resistant internal threads. Helical Inserts are engineered to withstand temperatures up to 800 degrees Fahrenheit.

Before installation, the diameter of a helical insert will be larger than the tapped hole, but 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.
