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.

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.

Smoothly install these inserts for strong threads near the edges and corners of soft metal surfaces. They’re lubricated to prevent sticking as you thread them in. Since these have thinner walls than our key-locking and thread-locking inserts, they don’t need as much space and won't bulge or crack the material. The knurls press (swage) into the material to keep inserts in place when you tighten or loosen a screw.

To install these inserts, you need a drill bit, a counterbore, a standard tap, an installation tool, and a hammer. Drill a hole, counterbore the top, and tap it. Place the insert into the installation tool, then hand-tighten it into the tapped hole. Strike the tool to secure the insert and drive the knurls into the surrounding material.

Add strong threads to the edges of soft metal without bulging or cracking the material. These inserts have thinner walls than our key-locking and thread-locking inserts, so they don’t need as much space around them. The knurls press (swage) into the material to keep inserts in place when you tighten or loosen a screw.

Place the insert into the installation tool, then hand-tighten it into the tapped hole. Strike the tool to secure the insert and drive the knurls into the surrounding material.

Keep threads clear and prevent leaks. These inserts have a closed end that blocks debris and fluids from entering parts. Keys drive into soft metal, such as aluminum, so they don’t slip or rotate in the hole. Comparable to Keensert inserts, they’re more secure than thread-locking inserts.

Add strong threads in soft metal, such as aluminum. The keys on these inserts drive into holes to hold more securely than thread-locking or helical inserts. They prevent slipping and rotating, so they’re stable enough for use in vehicle or aerospace parts that experience heavy vibration. 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.

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.
