Un-threaded applications require self-threading nuts or Push-nut fasteners. Commonly referred to as counter nuts, stamped sheet metal check-nuts or self locking counter nuts. Also very light weighted. So they also host a low profile. And tightened with an internal wrench or fingers. And it also provides a vibration resistant locking action. So usable in small, tricky areas suffering from space restrictions. Thus available in different range of sizes also.


Pal nuts come in a variety of sizes, design features to insure the success of your application.

It incorporate a design principle that has stood the test of over 60 years. Because these nuts may be used alone for load-carrying in light-duty assemblies. To assure tightness of high-stress assembly. So 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:  Pre – assembled 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: Pressed onto hollow plastic bosses. Where they minimize splitting and stripping.

Push-nut bolt retainers: Temporary fasteners that hold pre-inserted bolts in place until they reach final assembly.
