Features

  • Helical inserts, also known as screw thread inserts and helicoil inserts, are coiled wire inserts used to restore stripped threads and strengthen bolted connections.
  • These coils are broader than the tapped hole. When the bolt is screwed down after they are inserted into the hole, the coil expands and forms a tight & secure seal against the threads.
  • Helical inserts provide a permanent bond that is stronger than the original bolt fastening.
  • Heli-Coil nitronic 60 thread repair inserts expand upon being inserted via installation tools.
  • They are also used for converting standard threaded holes to accept metric fasteners.
