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.

Stainless Steel Snap-In Nuts
For excellent corrosion resistance in most environments, these nuts are made of 18-8 stainless steel. Snap them into square holes in thin material, and the mounting legs expand to lock them in place. Also known as cage nuts, the threads float inside the cage, so you can fasten a bolt at a slight angle to align off-center parts. These nuts are often used to mount servers and other equipment in electronics racks. They may be mildly magnetic.
Install these nuts by hand, with pliers, or with a snap-in nut installation and removal tool.

Easy-to-Install Snap-In Nuts
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. Once installed, they stay put. They meet DIN EN 61373, so they’re certified for use in environments with heavy vibration—think a bumpy railcar. GR-63-CORE tested, they’ve also passed earthquake simulations. In your facility, this means you can trust them to hold tight to sensitive equipment, like the servers suspended on your electrical racks.
Also known as cage nuts, they come in two parts—the cage and the nut—that you combine before installation. Threads float inside the cage, so you can fasten a bolt at a slight angle to align with off-center parts.

Snap-In Nut Installation and Removal Tools
Your fingers will thank you later—these tools compress the legs of snap-in nuts so they’re easy to install and remove. This is especially helpful if you’re installing a bunch back-to-back.
Style A tools work like a shoehorn. Angle one of the nut’s legs into the hole, then hook one of the tool’s prongs under the other leg to pull the nut into place.
Style B tools compress both nut legs simultaneously, so you can pop nuts in or out with a pinch. Simply squeeze the handle like a nail clipper. To grip nuts of different sizes, adjust the screw to open and close the end.
Style C tools are the most ergonomic. Just like a screwdriver, they have a cushion grip and a long handle for leverage. Dip one of the nut’s legs into the hole, then use the tool’s curved lip to tuck in the other leg, pulling the nut into place.
