Single Thread High-Torque U-Nuts are equally at home on metal or plastic. These unique fasteners bring extra strength, reliability and economy wherever vibration, impact, or migration prevail.

They accept power driven screws readily, discourage cross-threading, won't clog with paint or freeze to screw threads. They are self-retaining over a wide range of panel thicknesses, yet permit trouble-free removal. Unusually high clamp loads are attainable. Prevailing torque is inherent in the design.
