    Image of Product. Front orientation. Threaded Inserts. Tapered Heat-Set Threaded Inserts For Plastic.
    Tapered at one end, these inserts are easier to align in a hole during installation than straight inserts. Use a drill bit to create a straight hole, then taper the top half. Once installed, heat the insert with a soldering tip to melt the surrounding plastic.
    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.

    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.
    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.

    Tapping Threaded Insert Assortments for Soft Metal

    Image of Product. Front orientation. Threaded Inserts. Tapping Threaded Insert Assortments for Soft Metal.
    Cut a variety of thread sizes into aluminum and other soft metal—no taps required. These inserts cut their own threads and lock into material, so they won’t budge when you install or remove a screw. To install inserts with a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into a drilled hole. If you need to add a lot of threaded connections quickly, use an installation tool (not included) with a ratchet wrench or drill press. These inserts are comparable to Tap-Lok inserts.

    Pronged

    Restore, reinforce, or create threads in metal. The tough coils on these inserts expand once installed to anchor in a tapped hole. Also known as Heli-Coil inserts, they're often used in engine heads and machinery housings where strong connections are critical. Unlike threadlocking inserts, you can remove and reuse them without them losing their strength.
    Installation requires a drill bit, a helical insert tap, and an installation tool.
    Pronged—The prong attaches to an installation tool for precise control as you drive inserts in. Remove the prong with a punch or break-off tool before inserting a screw.

    Add strong, reusable metal threads to plastic. These inserts have external threads that bite into your material to resist pull-out better than press-in inserts. They're a more durable solution than threads cut directly into plastic. Inserts also have flutes that guide loose chips up and out of the way to keep threads clean. To install inserts with a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into a drilled hole. You can save time by using an installation tool with a ratchet wrench or drill press. Also known as Trisert inserts.

    Mold the strongest metal threads into plastic parts. Designed for injection molding, these inserts become inseparable from your part. They form a stronger bond than heat-set and press-fit inserts and are better for frequent use than threads cut directly into material. Unlike heat-set inserts, they can be used in a wide variety of plastics, including thermoset plastics that can’t be reformed.
    To install, position these inserts in your mold cavity with a core pin (not included).

    Twist-Resistant Press-In Threaded Inserts for Plastic

    Image of Product. Bottom orientation. Threaded Inserts. Twist-Resistant Press-In Threaded Inserts for Plastic.
    The hex-shaped body resists loosening and twisting in round holes for a more secure hold than other press-in inserts for plastic. Unlike screw-to-expand inserts, these inserts stay put even before you screw in a fastener. However, they may lose strength if screws are repeatedly removed and reinserted. Install inserts with an arbor press or similar pressure tool.
    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.
    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.

    High-Speed Steel—These taps resist heat and wear to stay sharp.
    Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.
    Bottoming Chamfer—Cut all the way to the bottom of blind holes with taps that have the shortest taper. Since these require the most force to turn, they’re often used to finish holes started by taper- or plug-chamfer taps.

    The closed end prevents molten plastic from seeping in and clogging the threads. Designed for injection molding, these inserts become inseparable from your part. They form a stronger bond than heat-set and press-fit inserts and last longer than threads cut directly into material. Unlike heat-set inserts, these work in a wide variety of plastics, including thermoset plastics that can’t be reformed.
    To install, position these inserts in your mold cavity with a core pin (not included).
