Ideal for use with plastic, threaded inserts from Spiralock provide superior torsional and pullout properties.
Our Ultrasonic Threaded Inserts for Straight Holes allow for a self-aligning lead-in that provides for accurate alignment prior to installation.
Ultrasonic installations of these inserts offer higher torsional and pullout properties than cold press-fit methods. High-frequency vibrations generate 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 re-solidify leaving the insert securely fit in place.
