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

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.

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

A flexible shank allows these rivets to be removed and reused. You need access to only one side of the material to install.
