Heat-Set Inserts

Heat-set inserts add threads to any part made from a thermoplastic, so that it can accept bolts and screws. They work by softening the surrounding material as they are being installed. Once a heat-set insert is installed, the plastic surrounding the insert establishes a secure bond between the metal insert and the thermoplastic.
