Grounding Snap-In Nuts
Pave a safe path for electricity—these nuts dig into the mounting surface and cut through coatings to touch the metal below for a proper ground. They’re often used to mount servers and other equipment into electronics racks. All meet EIA-310 (Electronic Industries Alliance) specifications for use in standard 19" electronics racks. Simply snap these nuts, also known as cage nuts, into square holes.
Style A nuts are green, a color commonly used to identify grounding components. They include a bolt with a serrated flange—while the nut’s teeth bite into one side, the bolt's serrations bite from the other. Install the nut by hand, with pliers, or with a snap-in nut installation and removal tool.
Style B nuts have a flexible plastic casing, so you can install them with a pinch. Unlike rigid snap-in nuts, you can squeeze them into a hole from either side. As you fasten a bolt, the nut in the casing is pulled up, pushing its teeth into the mounting surface.
