RT™ Free-Running Locknuts

PEM RT™ Free-Running Locknuts feature all-metal construction and are resistant to vibrational loosening. These locknuts from PEM allow the screw to turn freely until a clamp load is applied, and the modified thread angle on the loaded flank provides a vibration-resistant locking feature. The back side of the panel is flush or sub-flush for screw installation, and the locking feature reusability is not affected by the number of on/off cycles.
