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

The S-style design provides more strength than other no-slip clip-on nuts.

A hex-shaped barrel allows these clip-on nuts to be gripped with a wrench to hold them in place when tightening a screw. They have multiple threads for more thread engagement than low-profile clip-on 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.

Stainless steel snap-in nuts have excellent corrosion resistance in most environments.
