Here's how to remove key locking threaded insert tutorial
Step 1 : Drill put the material between the locking key and the internal thread to specified depth.
Step 2 : Deflect locking keys inward and break off.
Step 3 : Remove the insert from the hole by winding it out using a screw extractor or similar type tool.
Step 4 : A new key locking threaded insert of exactly the same size can be installed in the original hole.

Ultimate Security: Stainless Steel Key-Locking Inserts

Top Screw’s Key-Locking Threaded Inserts provide high-strength permanent threads in parent materials, offering superior resistance to pull-out and torque-out.

How Vibration Resistance Works: The core advantage lies in the Mechanical Keys. Once the insert is threaded into the hole, the pre-installed keys are driven down into the parent material. This creates a positive mechanical lock that prevents the insert from rotating due to vibration or torsion, ensuring the integrity of the joint under the most demanding conditions.

Ideal Industries:

  • Aerospace & Defense: Extreme pressure environments such as aircraft engines and airframe structures.

  • Automotive Industry: Engine components, drivetrain systems, and aftermarket tuning parts.

  • Heavy Machinery: High-impact applications including mining equipment and construction machinery.

  • Electronics & Energy: Wind turbines and railway signaling equipment.

 these inserts are the go-to solution for high-vibration environments where thread failure is a safety concern.

Comparison with Self-Tapping Inserts: While Self-Tapping Inserts offer a quick, one-step installation for softer materials like aluminum or plastic, Key-Locking Inserts are designed for maximum reliability in both hard and soft materials. The key-locking mechanism provides a significantly higher level of vibration resistance compared to the friction-based locking of self-tapping designs.
