Steel Snap-In Nuts
Snap these nuts—also known as cage nuts—into square holes in thin material. They’re often used to mount servers and other equipment in electronics racks. Threads float inside the cage, so you can fasten a bolt at a slight angle to align off-center parts. Mounting legs expand to lock these nuts in place.
Install these nuts by hand, with pliers, or with a snap-in nut installation and removal tool.
Black-phosphate steel nuts are mildly corrosion resistant in dry environments.
Zinc-plated steel nuts resist corrosion in wet environments.

No-Slip Clip-On Barrel Nuts
These clip-on nuts have a barrel with multiple threads for secure thread engagement. Also known as U-nuts, they squeeze both sides of thin panels for a tighter grip than J-nuts.

Clip-On Nut Assortments
Keep a variety of clip-on nuts on hand to create fastening points for screws. Simply slide these nuts onto the edges of thin panels.
Low-profile nuts are for low-clearance applications. No-slip nuts squeeze both sides of the panel for a tight grip. They’re also known as U-nuts. Barrel nuts have multiple threads for secure thread engagement.
