Choose the right threaded insert for your application and learn how to install it securely.
Flanged Tapping Inserts for Softwood
The flange keeps these inserts from being pulled through a hole and provides a load-bearing surface. They have large threads that cut into softwood for a strong hold. Made of zinc alloy, they have mild corrosion resistance. Install using a hex driver or an installation bit and drill for faster installation. Installed length includes the flange.
