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.
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.

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.
Zinc-plated steel nuts are corrosion resistant in wet environments.
Black-phosphate steel nuts are mildly corrosion resistant in dry environments.

Equipment Installation Supports for Electronics Racks


Shelve your worries about dropping heavy and valuable rack components, from servers to router shelves. These supports create temporary ledges to let equipment—and your arms—rest as you set up your electronics rack. Each pack includes four supports, one to prop up each corner of the equipment. Simply snap them into the rack’s rail just below the level where you want to mount equipment. When you’re done installing, pop them right out.
