What Are Cage Nuts Used For?

Cage Nuts, also known as clip nuts or captive nuts, are commonly used in rack mounting systems, industrial cabinets, and telecommunication enclosures. Their design — a square nut held inside a spring-steel cage — provides flexibility, allowing users to install threaded fasteners into panels with square holes quickly and securely.

As a professional cage nut supplier, Xinchi is glad to provide some common uses of cage nuts.

Cage Nut in Server Racks and Network Cabinets

Cage nuts are widely used in server racks, data center cabinets, and network enclosures.
They create threaded anchor points for installing devices such as:

• Servers and switches

• Patch panels

• Routers and PDUs

Because most rack rails have square mounting holes without internal threads, using cage nuts makes it easy to attach equipment firmly while maintaining flexibility for upgrades or reconfiguration.

Cage Nut in Telecommunication and Electrical Enclosures

In telecommunication systems and electrical cabinets, Cage Nuts enable quick installation and removal of modules, control panels, and distribution components.
Their floating nut design helps align screws even when panels are slightly misaligned, improving assembly efficiency and reducing equipment damage risk.

Cage Nut in Industrial and Machinery Applications

Cage nuts are also essential in industrial machinery, automation systems, and manufacturing equipment.
They provide reliable fastening in environments with vibration or frequent maintenance.
Thanks to the spring cage, the nut remains stable under stress, ensuring long-term mechanical stability.

Cage Nut in Furniture and Display Equipment

In modular furniture, exhibition stands, and display racks, cage nuts are used for repeated assembly and disassembly.
The spring cage structure keeps the nut in position while allowing the panels to be securely locked, offering a durable and reusable connection solution.

Advantages of Using Cage Nuts

Using cage nuts offers multiple practical and cost-saving benefits:

• Enable universal mounting flexibility without pre-threaded holes

• Allow easy replacement of damaged nuts without re-tapping

• Prevent wear on expensive rack threads

• Support multiple thread sizes (M5, M6, M8)

• Provide excellent load-bearing and anti-vibration performance

How to Choose the Right Cage Nut

When selecting cage nuts, consider the following factors:

• Thread size: M5, M6, or M8 depending on load and screw size

• Panel hole size: Ensure compatibility with the square hole dimensions

• Material: Carbon steel or stainless steel

• Surface treatment: Zinc plating, nickel plating, or black oxide

• Load requirement: Match the nut strength with your equipment weight
