With several server rack variations available, it may feel overwhelming trying to find the right equipment and accessories. For example, rack screws are available in all shapes and sizes. These are essential accessories in the workplace as they allow for component modification and assembly.

In this article, we will explain the different types of rack screw shapes and sizes. We will also discuss important features of each variation. By doing so, you can find the right accessories for your networking equipment. 

The Different Types of Rack Screw Shapes 

Square rack screw holes are the most commonly used in current IT equipment. These types of rack screws are ⅜” x ⅜” and 1.5mm to 3mm thick. 

Why is this the most popular type of rack screw hole?

Square rack screw holes are popular because of their versatility and ease of use. They are compatible with all types of rack screw sizes. In addition, their width and thickness allow them to safely support any type of server rack equipment. 

Next, there are threaded rack screw holes. Due to the design, this type of rack screw hole allows for simplified component installation. Rack screws fit easier and more securely with threaded holes. 

Lastly, round rack screw holes are commonly seen in equipment manufactured by Dell, IBM, and HPE. However, this variation is less popular as most prefer the versatility of universal square holes or the security of threaded holes. 

It is important to note the differences between square holes and threaded holes. Square hole racks tend to be more affordable; however, they do require the use of cage nuts. Alternatively, racks that utilize threaded holes don’t require additional accessories. While there is no incorrect choice, certain options may either save time or save money. 

The Different Types of Rack Screw Sizes

Along with the various types of rack screw holes, there are also different types of rack screw sizes. This is equally as important as different server racks require different types of rack screws. Therefore, to avoid any potential mishaps, it is important to understand the different variations. 

To begin, there is the 10-32 rack screw. Often called the “original” rack screw, the 10-32 model is the most popular and most commonly used. The “10” refers to the size of the screw, with a diameter of 3/16”. “32” is the number of threads per inch.

Next, the 12-24 rack screw is bigger with a diameter of 7/32”. Despite being larger, it features fewer threads per inch at 24. This type of screw is typically used in pre-threaded racks.

Finally, there is the M6 rack screw. This product is named differently from its counterparts because the M6 rack screw originates from Europe. It is the largest rack screw, with a diameter of 6mm or slightly less than ¼”.
