What is Cage Nut? Properties, Uses and Application

Cage Nuts

The importance of a nut and bolt combination cannot be overstated when it comes to fastening or securing objects. However, have you ever heard about a cage nut? Cage nuts are integral to industrial and commercial equipment, securing racks and cabinets and providing an easy mount for servers and other IT equipment. In this blog post, we’ll provide an in-depth understanding of what a cage nut is, its properties and uses, and its applications.

What is Cage Nut?

Cage nuts are a type of fastener used in racks and cabinets to mount hardware. They consist of two parts: the cage, which is typically made of metal or plastic and acts as a backing nut, and a conventional nut that tightens against it. The unique design helps create even pressure on the rack when tightening, making installation easier than with other fasteners.

Cage Nut Properties:

Cage nuts are made of high-strength lightweight metal like stainless steel, aluminium, or zinc-plated steel. They are designed with a captive nut in a spring steel cage, which adds stability, strength, and alignment to help speed up and simplify the installation process. In addition, the cage around the nut can be useful for holding a bolt or screw head in place while fastening.

Cage Nut The Uses:

Cage nuts are commonly used in IT infrastructure, telecommunications, and aerospace industries to mount servers, routers, switches, and other types of equipment. They are also useful in industrial settings, such as securing cabinets and racks in manufacturing. These nuts can also help optimise space since they allow for quick adjustments or removal of equipment.

Cage Nut Applications:

Cage nuts are often used in data centres to secure IT equipment like servers, switches, patch panels, and other devices. Additionally, they are used in telecom companies for mounting devices like modems, wireless access points, and routers. They are also used in the aviation industry to reinforce the aircraft structure with supporting brackets. Cage nuts can also be found in the automotive industry to secure battery leads and accessories in the engine bay.

How to Use Cage Nut:

Using cage nuts is a simple process. Begin by inserting the cage nut into the panel hole, which should snap firmly into place. Once the cage nut is in place, you can then insert the screw or bolt through the mounting hole and then tighten it. The spring steel cage will compress and grip onto the screw or bolt to provide a secure hold.


In conclusion, a cage nut is a crucial component in various industries for mounting and securing equipment adequately. Cage nuts offer an easy and fast method for installing equipment, even in tight and awkward spaces. They offer excellent stability and security, ensuring the equipment is firmly in place. This blog post comprehensively explains cage nuts, their properties, uses, applications, and how to use them.
