Tapping Inserts for Plastic

Also known as Trisert inserts, these cut threads into plastic and have better holding power than press-fit inserts. Flutes channel loose chips up and out to keep threads clean during installation. Made from brass, they’re corrosion resistant, electrically conductive, and nonmagnetic. Install in a drilled hole using a required installation tool.

Tapping Inserts for Soft Metal

Also known as Tap-Lok inserts, these inserts cut their own threads in soft metals such as aluminum, so there’s no need to tap the hole. Install them into a drilled hole with an installation tool and a ratchet wrench. Installation tools can also be placed in the chuck on a drill press and turned by hand.

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.
