    Screw-Locking Helical Threaded Inserts

    The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration. Use these inserts to create or repair threads in pumps and other machinery that shakes and rattles. 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.
    Prongless—Without a prong to break off and retrieve, these inserts save time and avoid leftover debris in holes.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Screw-Locking Seize-Resistant Helical Threaded Inserts

    Image of Product. Bottom orientation. Threaded Inserts. Screw-Locking Seize-Resistant Helical Threaded Inserts.
    Screws won't get stuck or come loose with these inserts. A dry film on the surface lubricates fasteners during insertion to prevent sticking and binding. Once installed, the irregularly shaped threads tightly grip screws to keep them in place under vibration. 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.
    Dry-Film-Lubricated 18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Lubricant-Free Screw-Locking Seize-Resistant Helical Threaded Inserts

    Image of Product. Bottom orientation. Threaded Inserts. Lubricant-Free Screw-Locking Seize-Resistant Helical Threaded Inserts.
    Keep screws from getting stuck or backing out with inserts that also won’t contaminate areas such as clean rooms and labs. Inserts are made of Nitronic 60 stainless steel, so you don’t need lubricant or coatings to prevent wear from repeated installation. They have irregularly shaped threads that grip the screw to resist loosening under vibration. 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.
