          Quik-Tek Inserts

          QT Series Inserts

          The advantages:
          Ideal for thermoplastic parts
          Especially designed for thermal installation
          Screw-locked and low-tension anchoring
          High pull-out values
          Efficient installation due to single-spindle, 
          multiple spindle or automatic machines with preheating device
          Designed for thermoplastic plastics (PPS. ABS、PP etc.)    

             
          Installation:
          The QT thread insert is heated to the melting temperature of the plastic.
          As a result of the heat transfer upon insertion,the plastic is plasticised for a short
          time and flows into the undercut of the thread insert.Upon cooling,a low-stress
          interference is realised.

          What can I use to rethread a bolt hole?

          To retighten a bolt hole, you can use a variety of methods and tools, depending on the condition of the hole and the materials involved. Here are some common options:

          Epoxy resin or thread repair glue
          Materials Required: Epoxy or thread repair glue.

          Steps:
          Clean the area: Make sure the hole is clean and free of debris.

          Apply Epoxy: Fill damaged threads with epoxy or adhesive.

          Allow to Cure: Allow the adhesive to cure according to the manufacturer’s instructions.

          Re-Thread: Once cured you can use a tap to create new threads in the epoxy.


          The method you choose depends on the extent of the damage and the material of the bolt hole. For most applications, using a tap and die set or a thread repair insert is the most effective way to re-tap a bolt hole. Always make sure you have the correct size and type of tool for the job.
