          L4022 Tangfree coil thread insert

          L4022 Tangfree Screwlock thread insert

          The advantages:
          L4022 Screwlock has the same advantages as L4020.
          In addition, there is a screw-locking area.  The screw is locked by one or several polygonal-shaped threads clamping the flanks of the screwed in screw.  The elastically resilient frictional locking results in prevailing torques similar to the specifications of ISO 2320.  These screw locking torques meet the demands of technical delivery terms regarding international standard specifications.  
          L4022 Tangfree Screwlock can only be used with screws of higher property classes (8.8 and higher).  Common lubricants according to the manufacturers’recommendations shall be used for highly alloyed screws.  This thread insert is widely used in the aviation industry.
           
          Installation:
          You do not need a tang to install these thread inserts. Therefore, tang break and 
          removal are not required. Combined with the matching installation tools

          How do you install wire thread inserts?

          Installing a wire thread insert requires several key steps to ensure a correct and secure installation. Here is a step-by-step guide to installing a wire thread insert:

          Installation steps:
          Prepare the area:
          Ensure the work area is clean and free of debris. Wear goggles to protect your eyes.

          Drilling:
          Use a drill bit that matches the size of the wire thread insert being used. Drill out any damaged threads and create a clean hole. Make sure the hole is straight and to the correct depth.

          Knock hole:
          After drilling, use a tap to create new threads in the hole. Apply lubricant to the tap to reduce friction and make the process smoother. Turn the tap slowly and steadily, occasionally reversing it to clear out any debris.

          Insert the wire thread insert:
          Insert the wire thread insert into the newly tapped hole using a suitable installation tool. The insert should be screwed in until it is flush with the surface of the material. If the insert has a tang, this will assist installation.

          Break the handle (if applicable):
          If the blade has a tang, use a snapping tool to snap it off at the designated location. This will ensure that the blade is fully secured and ready for use.

          Final Check:
          Check the installation to make sure the insert is properly seated and there are no obstructions. You can now install the screw or bolt using the newly created threads.

          Tip:
          Always refer to the manufacturer’s instructions for specific details on the size and type of insert used.

          Make sure the drill and tap sizes are compatible with the wire thread insert specifications.

          If you are unsure of the process, consider practicing on scrap materials first.

          By following these steps, you can effectively install wire thread inserts and restore functionality to damaged threaded holes.
