Push-on and turn-on fasteners

Push-on and turn-on fasteners are self-locking and self-threading fasteners respectively that replace standard nuts. These fasteners are pushed or screwed onto studs molded into a part, capturing the mating component. They are easy to use, inexpensive and vibration resistant, and provide a light to medium duty assembly, where clamp load requirements are minimal.

Push-on fastener for a permanent assembly

The type of fastener shown below produces a permanent assembly, whereas a removable assembly can be made with a Tinnerman® clip in combination with a stud with a D-shape cross-section.

The self-threading nut in the figure below also produces a removable assembly and allows for some control over the clamp force. Figure A is a push on nut and Figure B a self threading nut.
