The Ultrasonic Threaded Insert, part number 94100, from Stanley Engineered Fastening - Spiralock, is designed for use in tapered holes, facilitating rapid and precise alignment before installation. This insert utilizes high-frequency vibrations to generate frictional heat at the interface between metal and plastic, allowing the plastic to melt slightly and flow into the insert's knurled serrations, barbs, and undercuts. Once cooled, the plastic resolidifies, securing the insert in place. This method provides superior torsional and pullout strength compared to traditional cold press-fit techniques, making it suitable for applications requiring reliable fastening in high-vibration environments.
These inserts are designed for use in tapered holes, which allows for rapid and 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.
