About Threaded Inserts

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

Key-Locking Threaded Inserts for Soft Metal

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.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

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.

Key-Locking Threaded Insert Drivers

Place the tip of these tools into a key-locking insert after you've threaded it into a hole with your fingers. Then, strike these tools with a hammer to drive the keys into the material and secure the insert. They’re compatible with Keensert inserts.

Choose the tool that matches your insert’s thread size and tap thread size.
