Keyed Inserts and KEENSERTS Installation
Assembly
American Precision Assembly provides precision installation of keyed inserts and KEENSERTS threaded inserts used in aerospace, defense, and high-performance mechanical assemblies. These specialized inserts create strong, durable internal threads in materials that may otherwise be too weak to support repeated fastener loads.
Keyed inserts, commonly referred to as KEENSERTS or key-locking threaded inserts, are solid threaded bushings that include locking keys designed to permanently secure the insert within the parent material. These inserts are widely used in aerospace systems where reliable threads, vibration resistance, and high load capacity are critical.
American Precision Assembly installs key-locking threaded inserts using controlled installation procedures and specialized aerospace tooling, ensuring precise alignment and secure mechanical locking.
What Are Keyed Inserts and KEENSERTS?
Keyed inserts, often called KEENSERTS, are solid threaded inserts that contain internal and external threads along with mechanical locking keys. After installation, the keys are driven into the surrounding material to prevent rotation and provide a secure mechanical lock.
These inserts are designed to:
Because the locking keys mechanically anchor the insert in place, keyed inserts resist rotation and pull-out even in demanding aerospace applications.
- Reinforce threaded holes in softer materials
- Repair damaged or stripped threads
- Provide high-strength internal threads
- Prevent loosening in high-vibration environments
Our Keyed Insert Installation Capabilities
American Precision Assembly performs precision installation of keyed inserts and KEENSERTS threaded inserts for aerospace components and mechanical assemblies requiring strong, reliable threads.
Why Keyed Inserts Are Used in Aerospace Components
Threaded connections in aerospace systems must remain secure despite vibration, temperature changes, and repeated maintenance cycles. Keyed inserts provide a durable threaded interface that resists stripping and loosening.
Advantages of KEENSERTS and key-locking inserts include:
These characteristics make keyed inserts a trusted solution for high-reliability aerospace assemblies.
- High pull-out and torque resistance
- Strong threads in lightweight materials
- Resistance to vibration and rotation
- Reliable performance under repeated fastener removal
