Threaded Palnuts®

Palnut® lock nuts incorporate a design principle that has stood the test of over 60 years. These nuts may be used alone for load-carrying in light-duty assemblies or they may be used on top of ordinary nuts to assure tightness of high-stress assemblies. They offer impressive savings over alternative fasteners in initial cost, assembly time, weight and space. They are removable, reusable, self-cleaning. They are unaffected by temperatures up to 400°.

Tension nuts are preassembled on adjusting screws to a predetermined point. Subsequent turning of the screw advances the tension nut until it touches the work. Barbs on the nut base then "bite" and resist further turning.

On-sert fasteners are pressed onto hollow platic bosses where they minimize splitting and stripping.

Pushnut bolt retainers are temporary fasteners that hold pre-inserted bolts in place until they reach final assembly.
