For excellent corrosion resistance in most environments, these nuts are made of 18-8 stainless steel.

Pinch the flexible plastic casing of these nuts to add threads to thin metal. Unlike typical rigid snap-in nuts, these squeeze into a square hole from the front or back of your material.

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

Use these light-duty clip-on nuts in low-clearance applications.

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.

Threads float inside the retainer of these metric nuts so you can install a bolt at a slight angle to align with off-center parts.

Your fingers will thank you later—these tools compress the legs of snap-in nuts so they’re easy to install and remove.
