    About Threaded Inserts

    Choose the right threaded insert for your application and learn how to install it securely.

    Heat-Set Threaded Inserts for Plastic

    Create a secure base for fasteners in plastic, including brittle 3D printed parts. Press these inserts into straight holes that have been drilled, printed, or molded into plastic. Then, heat them with a soldering tip to melt the surrounding material. As the plastic cools, it fuses to the sharp, diagonal ridges around the inserts, which prevents them from being twisted or pulled out. The interior is fully threaded, so you can access the threads from both sides of a through hole. Also known as Chevron and headed inserts.
    Flanged Profile—Flanges on the insert create a load-bearing surface that prevents cracks or deformation in the base material. They also curb overtightening and keep inserts from getting pulled out or through.
    Brass—Conductive and nonmagnetic, these inserts are useful for electrical applications. They resist moisture but aren't as strong as steel inserts.
    Lightweight Aluminum—At one-third the weight of steel or brass, use these inserts in robotics, aerospace parts, and other applications with strict weight limits. They also resist rust about as well as stainless steel but aren't as strong. Since inserts are lead-free, they can be safely recycled.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals. Since they’re lead-free, they can be safely recycled.
