Tool Highlight: Cage Nut Tool
In the world of data centers there are several kinds of rails used to mount server and switch devices. From two post rails to four post rails, square hole and round hole. The most commonly seen rail by Silverback is the four post, square holed variety. For more basic information on rails check out our knowledge base article on the standards used: Rail Standards.While called a 19″ rack, there are no actual dimensions within the rack that equal 19″, they are referring to the width of the device faces that will fit within the rails. Rack units on the other hand are a steady and consistent 1.75″ all the time, every time. When working with round holed racks, mounting a device is as easy as putting it where you want it and zipping in a few screws. When working with square holed racks, things become a bit more interesting as they bring the need for cage nuts.
When working with cage nuts, any experienced data center tech will tell you; they can become frustrating quickly. The basic principle of the cage nut is a square nut inside of a thin metal casing with wings that hold the nut to the rail. With classes such as M5, M6 and 1032 – each one having their own corresponding screw type – it can get confusing easily. Luckily it doesn’t mater what class of cage nut or who made the square holed rail, there is a tool that helps to avoid pinched fingers and curse words in the data center. The cage nut tool comes from many manufacturers in various types. The two common types are a flat metal bit and a nail clipper-like crimper that pinches he nut into place. We here at Silverback prefer the simple flat metal bit for many reasons; the biggest of which is it’s ability to get into small places. When you’re installing a single unit device between two others the crimper simply doesn’t offer the versatility of the flat tool.
While there are plenty of ways that people will tell you to use a cage nut tool, we’ve put together a small training video that explains how Silverback uses them. Enjoy! Training Series: How to use a cage nut tool.
