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.

Heat-Set Inserts for Plastic
Install these inserts into plastic parts to create a secure base for fasteners. Also known as Chevron and headed inserts, they are often used to strengthen mounting holes on brittle plastics, such as on 3D printed parts. Unlike plastic threads, which wear down with repeat use, these brass threads hold their shape over a long life. Press inserts into straight holes that have been drilled, printed, or molded into plastic parts, then heat them with a soldering tip to melt the surrounding plastic. As the plastic cools, it fuses to the sharp, diagonal ridges around the inserts, which withstand torque and prevent the inserts from being pulled out. The interior is fully threaded, so you can access the threads from both sides of a through-hole.
Flanged inserts have a wider end than standard inserts, which gives them a larger load-bearing surface and makes them harder to pull out. The flange also gives you a larger contact area for soldering. When threading into the flanged side, these inserts prevent over-tightening, which can cause brittle plastic to crack.
