Advantages:
Self-tapping, self-locking
Provide stronger, more durable permanent threads in soft metals and plastics
Supply permanent threads in cast iron that will not gall, seize, corrode or strip
Offer strong resistance to rotation and pull-out
Lead on both ends simplifies installation
Ideal for automated production
Description
TRISERT Inserts are internally and externally threaded metal bushings that are installed in plastics, soft metals and wood 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.
