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.

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.

Turn these tools by hand to install low-profile rivet nuts. The required mandrels are sold separately. To use, thread the nut onto a mandrel of the same size, then place it into a hole, push down on the tool's T-handle, and turn clockwise.

Add permanent threads to thin panels in seconds. The knurls on these clinch-style nuts deform and grip sheet metal to create a permanent hold. Push them into a drilled or punched hole with an arbor press around your workpiece to install—no messy welding required.

Add threads to sheet metal and panels in confined spaces with limited backside clearance. At installation, these compact nuts collapse into themselves and press slightly outward, creating snug-fitting threads half the length of a standard nut but just as strong. With a thin top flange that creates a near-flush fit, they're ideal for light duty fastening in small enclosures or housings.

Install these nuts using a hand- or power-driven rivet nut tool. In thick material, drill or punch a slightly larger hole to ensure the nut body expands uniformly.

Brass binding barrels and screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. Use them to anchor door closers, kickplates, and other architectural hardware. The barrel head is smooth with no drive to be tampered with on the outside of your door, and the screw has a flat head that sits flush with the surface for a finished look. The screw protrudes from the barrel to leave room for hardware. Install in a hole with a diameter equal to the barrel diameter. Barrel length and screw length are measured from under the head.

Quickly restore stripped threads—these inserts come with through-hole taps and installation tools. The tough coils on these inserts expand once installed to anchor in a tapped hole.

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.

Made from 18-8 stainless steel, these binding barrels and screws are chemical resistant and may be mildly magnetic. Use them to anchor door closers, kickplates, and other architectural hardware. The barrel head is smooth with no drive to be tampered with on the outside of your door, and the screw has a flat head that sits flush with the surface for a finished look. The screw protrudes from the barrel to leave room for hardware. Install in a hole with a diameter equal to the barrel diameter. Barrel length and screw length are measured from under the head.

Repair damaged threads or create new ones. These convenient assortments include helical inserts, an installation tool for each thread size, a drill bit, and a tap. The inserts are also known as Heli-Coil inserts.

Snap the drive prong from installed helical inserts to leave a flush thread ready for your fastener. These punch-style tools are compatible with both standard and screw-locking helical inserts. They work with a standard hammer—no special equipment needed.
