Cage Nuts

Cage nuts are versatile fasteners used in various industries for secure rack mounting of equipment and components. These nuts are designed to be used with square-holed racks and cabinets, providing a reliable and adjustable solution for installing devices such as servers, network equipment, and other electronic devices. Cage nuts feature a unique design that allows them to be inserted into square holes and then rotated to lock securely into place. This innovative design eliminates the need for additional hardware such as screws or tools for installation, making them efficient and time-saving components. In this comprehensive product description, we will explore the world of cage nuts, their types, materials, applications, installation methods, and the valuable contributions they bring to efficient rack mounting solutions.

What are Cage Nuts?

Cage nuts, also known as captive nuts or clip nuts, are specialized fasteners designed for mounting equipment in square-holed racks and cabinets. They are widely used in data centers, server rooms, network closets, and other IT installations, where secure rack mounting of electronic devices is essential. Cage nuts consist of a square nut housed in a spring steel cage with two or four flanges that extend beyond the nut's edges. These flanges allow the cage nut to be inserted into a square hole, and when rotated, the flanges grip the rack's edges, securely locking the cage nut in place. This unique design provides a reliable and adjustable mounting solution, allowing for easy installation and removal of equipment without the need for access to the rear of the rack.
