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

    Thread-Locking Threaded Inserts

    Image of Product. Bottom orientation. Threaded Inserts. Thread-Locking Threaded Inserts.
    With Loctite® adhesive already on the threads, these inserts won’t back out or vibrate loose. The adhesive reaches full strength after 72 hours. Unlike helical inserts, you can install them with a standard drill and tap. However, thread-locking inserts are difficult to remove and reuse.
    After drilling and tapping your hole, install inserts with a wrench or an installation bit. To use a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into the hole. For slotted inserts, you can drive with a slotted screwdriver instead.
    Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.
    Extra-Thick Wall—Stronger than standard- and thin-wall inserts, use them to reduce the size of tapped holes or replace threads that have been drilled out.
    Black Phosphate-Coated Steel—These inserts resist occasional moisture.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    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.

    Mil.-Spec. Key-Locking Threaded Inserts For Soft Metal

    Image of Product. Bottom orientation. Threaded Inserts. Mil.-Spec. Key-Locking Threaded Inserts For Soft Metal.
    These inserts are manufactured and tested to meet or compare to strict standards adopted by the U.S. military. The keys drive into aluminum and other soft metal for a secure hold that won't slip or rotate, even in vibrating vehicle or aerospace parts. These inserts are comparable to Keensert inserts.
    To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.
    Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.
    Extra-Thick Wall—Stronger than standard- and thin-wall inserts, use them to reduce the size of tapped holes or replace threads that have been drilled out.
    High-Strength Cadmium-Plated Alloy Steel—These inserts have the strength to stand up to high-pressure applications and a plating that helps screws thread in smoothly.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Helical Threaded 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.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Steel Socket Nuts

    Image of Product. Front orientation. Socket Nuts. Steel Socket Nuts.
    Also known as Allen nuts, use these with socket head cap screws in recessed holes and tight spaces that don't have enough clearance for a wrench. Tighten them with a 6-point hex key. They can also be used as an insert by pressing or drawing them into nonhardened steel, cast iron, or soft nonferrous metal or by molding them into plastic, ceramic, fiber, and similar materials. Made from alloy steel, they're comparable in strength to Grade 9 bolts.

    Screw-Locking Seize-Resistant Key-Locking Threaded Inserts for Soft Metal

    Image of Product. Bottom orientation. Threaded Inserts. Screw-Locking Seize-Resistant Key-Locking Threaded Inserts for Soft Metal.
    Create the tightest hold in aluminum and other soft metal without screws sticking. The lubricant on these inserts eases installation, and the irregularly shaped threads won’t let screws back out from vibration. Inserts have keys that drive into material to prevent them from slipping or rotating in the hole.
    To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.
    Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.
    Dry-Film-Lubricated 18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    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.

    Keep equipment level on slightly sloped and pitted floors with mounts that have a ball-and-socket joint in the base. For mounting versatility, you can install them in either threaded holes or unthreaded through holes at the bottom of equipment.
    Nickel-Plated Steel Base—With a shiny appearance, these mounts create a finished look. They're best for dry environments since the nickel plating offers minimal corrosion resistance.
    Zinc-Yellow-Chromate-Plated Steel Base—More corrosion resistant than nickel-plated steel, these mounts are suitable for damp environments. However, they won’t hold up to chemical cleaners, high-pressure washdowns, and other harsh conditions like stainless steel can.
    Black-Oxide Steel Base—With a matte black appearance, these mounts create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    303 Stainless Steel Base—The choice for most wet locations, these mounts can withstand repeated washdowns without corroding. However, they won't hold up to cleaning solutions that contain harsh chemicals like 316 stainless steel can.
    Delrin® Acetal Base—These mounts are economical yet resistant to grease, oil, and chemicals that pool on the floor. Often used on small, lightweight machines, they have about 25% the capacity of similarly sized metal mounts.
    Rubber Cushion—A cushion under the base grips surfaces so vibrating equipment doesn't slide. It also protects floors from scrapes and gouges.

    Wedge Anchors for Concrete

    Image of ProductInUse. Front orientation. Anchors. Wedge Anchors for Concrete.
    Image of Product. Front orientation. Contains Annotated. Anchors. Wedge Anchors for Concrete.
    Secure junction boxes, safety railings, and structural beams in concrete floors. These anchors have a wedge-shaped base that expands against the hole’s sides, forming a tight grip that withstands high pull-out forces. Since the grip is focused at the base, these anchors are best suited for concrete, which can handle the gripping pressure better than softer block and brick. However, they require holes that match the anchors' diameter exactly to achieve their pull-out strength, making them more difficult to install than sleeve anchors.
    To install, drive the anchor through your component into a drilled hole until the washer and nut meet the surface. Then, tighten the nut to expand the anchor base. Remove your component by unfastening the nut, but the anchor itself cannot be removed.
    Zinc-Plated Steel and Zinc-Yellow-Chromate-Plated Steel—The most common choice for areas with occasional exposure to moisture.
    Corrosion-Resistant Galvanized Steel—Combine the strength of steel with the rust resistance of stainless steel. These anchors are an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they’ll corrode or pit when exposed to salt water and chemicals.
    Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these anchors resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these anchors won't degrade when exposed to harsh weather, salt water, and most chemicals.
