Tri-Star Industries, Inc. Tapered Threaded Inserts H Series Short

H Series tapered threaded inserts for plastics outperform all competitive inserts for ultrasonic and thermal installation into thermoplastic or structural foam. Our customers confirm it. We’ve eliminated the outward stress that occurs with other insert designs during the installation process. Our proprietary “knuckle knurl” ensures a more uniform flow of material into the diagonal knurls and undercuts, ensuring a complete fill, reducing installation time and increasing holding strengths. The tapered insert design makes alignment faster and more accurate, reducing installation time.
