Description
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 repeated use these 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.Made with lead brass inserts are stronger than aluminum and other brass alloys but not as strong as stainless steel inserts. They have good corrosion resistance.
