Ultrasonic Threaded Inserts for Straight Holes

These inserts are designed for use in straight holes for which a self-aligning lead-in provides for accurate alignment prior to installation. With the use of high-frequency vibrations generating frictional heat at the metal to plastic interface, the plastic melts slightly and flows into the knurled serrations, barbs, and undercuts. The molten plastic will then resolidify leaving the insert securely fit in place. Ultrasonic installations of inserts offer higher torsional and pullout properties than cold press-fit methods.
