With flexible teeth that slide smoothly over threads of any pitch, these push nuts can be used alone for light-duty applications or as a jam nut.

Also known as flat-style speed nuts, these have large sides, so they're easy to push over threads by hand.

A flange distributes the load over a large area and reduces stress where the nut meets the material surface.
