How to install lockbolts

Apr 28 , 2024

Lockbolts are high-strength fasteners commonly used in various industries for joining applications where reliability and security are paramount. Proper installation of lockbolts is crucial to ensure optimal performance and integrity of the joint. Below is a step-by-step guide on how to install lockbolts:


1. Preparation:

  • Ensure that the materials to be fastened are clean and free from any contaminants.
  • Select the appropriate lockbolt size and type based on the application requirements.


2. Drilling:

  • Drill a hole through the materials to be joined. The diameter of the hole should be slightly larger than the diameter of the lockbolt body to allow for insertion.


3. Inserting the Lockbolt:

  • Insert the lockbolt through the prepared hole from one side of the joint.


4. Placing the Collar:

  • Place the collar over the exposed end of the lockbolt protruding from the opposite side of the joint.


5. Installation Tool Setup:

  • Set up the appropriate installation tool (lockbolt gun) with the correct nose assembly and mandrel.


6. Installation:

  • Position the installation tool over the collar and engage the tool with the lockbolt.
  • Apply pressure to the installation tool to compress the lockbolt and form the collar around the materials being joined.
  • Continue to apply pressure until the lockbolt breaks at the predetermined break point.


7. Inspection:

  • After installation, visually inspect the joint to ensure that the collar is properly formed and secured around the materials.
  • Perform any required testing to verify the integrity and strength of the joint.


8. Finishing:

  • If necessary, trim any excess lockbolt protruding from the collar using appropriate tools.


9. Documentation:

  • Record details of the installation, including the lockbolt type, size, installation parameters, and any test results, for future reference.


10. Safety Precautions:

  • Always wear appropriate personal protective equipment (PPE) when installing lockbolts, including safety glasses and gloves.
  • Follow all safety guidelines and instructions provided by the lockbolt manufacturer and installation tool supplier.


By following these steps carefully and adhering to safety precautions, you can ensure the successful installation of lockbolt fasteners for your application, providing reliable and durable fastening solutions.
