    Spring-Loaded Helical Threaded Insert Prong Break-Off Tools

    Image of Product. Front orientation. Threaded Insert Installation Tools. Spring-Loaded Helical Threaded Insert Prong Break-Off Tools.
    Cleanly snap prongs off installed helical inserts with just one hand. Because they work faster than standard prong break-off tools, these are a good choice when you have many prongs to remove. Press your tool into an insert to trigger the spring-loaded punch and snap off the prong.
    For Standard-Length Inserts—Use these tools for inserts that are 1 to 2 times as long as the diameter.
    For Long Inserts—Use these tools for inserts that are 2 1/2 to 3 times as long as the diameter.

    To remove installed helical inserts, place the tip of these tools into the insert and lightly strike the tool’s head. Then, turn the tool counterclockwise with pressure to extract the insert.
    Narrow Profile—The tip of these tools has a narrower angle than standard removal tools to reduce the chance it will dig into your material’s surface when you strike the tool.

    Fix threads in parts that rotate counterclockwise. Pair these inserts with left-hand-thread screws and turn them to the left to tighten. Also known as Heli-Coil inserts.
    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.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Install helical inserts and break off prongs with one tool and a hammer strike. These tools have a slot that grips your insert’s prong for turning both left- and right-hand threads. Slide an insert onto these tools and drive them a quarter-turn to half-turn below the material’s surface. Then, strike the end of the tool with a hammer to break off the prong. These tools work with pronged helical inserts.

    Left-Hand Thread Helical Insert Taps

    Image of Product. Front orientation. Taps. Left-Hand Thread Helical Insert Taps.
    Size holes for installing helical inserts that anchor left-hand bolts and rods. Helical inserts reinforce the connection between holes and fasteners that secure counter-clockwise rotating parts. Left-hand threads keep components such as flywheels and propellers from loosening and spinning off.
    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.
