Threaded Inserts

For prototyping and low volume we use Yardley “Trisert” threaded brass inserts. The insert is manually installed into the part with a Yardley “Trisert” hand tool.




Advantages
  • Self-tapping, self-locking
  • Provide stronger, more durable permanent threads in plastics
  • Offer strong resistance to rotation and pull-out
  • Lead on both ends simplifies installation


TRISERT Inserts are internally and externally threaded metal bushings that are installed in plastics and soft metals to provide stronger threads than the base plastic or metal can offer. They tap their own threads as they are driven (turned) into drilled or cored holes. The three, full-length, external flutes provide a balanced, full cutting action. Chips and dust are retained in these flutes and the inside threads stay clean. This is especially important in electronic or electrical work where contamination can cause serious problems.



To make installation easier, TRISERT Inserts have a lead on both ends permitting manual placement by feel and making hopper feed practical for automated production.
