Reducing the size of equipment and devices / Return and fall prevention of screws


  • The friction of the nylon adhered to the thread suppresses the return rotation of the thread.
  • Even if the tightening force is lost, the return rotation is suppressed, preventing the screws from falling off.
  • All head heights are 1.5mm or less.
  • For space-saving of equipment/devices and applications with limited overhead space.
