Also known as U-style clip on nuts, these nuts have a barrel with multiple threads for secure thread engagement.

Also known as U-nuts, these nuts squeeze both sides of thin panels for a tighter grip than J-nuts.

Because one leg is shorter than the other, you can adjust the position of these nuts before you insert a machine screw. Also known as J-nuts, they have a slightly looser fit on thin panels than U-nuts.

For a stronger grip than J-nuts, these nuts—also known as U-nuts—firmly squeeze thin panels from both sides. Use them as a fastening point for tapping screws.

Also known as G-nuts, these nuts have a G-shaped body that slips around the lip of a flanged panel.

These wing-head screws have a clip-on nut that allows you to mount them near the edge of a thin panel. Use them to lock and release access panels, doors, and covers with a quarter-turn.
