Fasteners play a vital role in various industries, including CNC machining. These small components are responsible for securely holding parts together, ensuring the structural integrity and functionality of the assembled products. In this article, we will delve into the world of fasteners, exploring different types and their significance in CNC machining.

1. Screws - The Backbone of Assemblies:

Screws are one of the most common types of fasteners used in CNC machining. They come in various sizes, materials, and head styles to accommodate different applications. Their primary purpose is to connect two or more objects together by creating sufficient clamping force. Screws typically require holes to be drilled prior to installation, providing a secure way of assembling two components.

2. Bolts and Nuts - Enabling Sturdy Connections:

Bolts and nuts form another crucial category of fasteners extensively utilized in CNC machining. Bolts are similar to screws but tend to be larger in size and range from fully threaded to partially threaded variations. Nuts, on the other hand, are designed to fit onto bolts securely, providing a threaded connection. This combination creates strong and lasting joints capable of withstanding heavy loads and vibrations.

3. Rivets - Invisible Strength:

Rivets offer a discreet and permanent joining solution to CNC machined parts. Typically made of metals such as aluminum or stainless steel, rivets consist of a cylindrical shaft attached using heat or pressure. Once installed, they cannot be disassembled without destroying them, making them suitable for applications where tampering isn't desired. Additionally, rivets provide excellent resistance against shear forces, adding reinforcement to automotive, aerospace, and structural assemblies.

4. Washers - Distributing Stress:

Washers act as essential accessories when it comes to enhancing the functionality and reliability of fastened connections. They prevent damage caused due to metal-to-metal contact by distributing the load and minimizing friction. Flat washers, spring washers, and lock washers are common variations used in CNC machining. By reducing stress concentrations, washers increase the longevity of fastened joints.

5. Inserts - Reinforcing Threads:

In certain cases, where threads need additional reinforcement or when joining dissimilar materials, inserts come into play. These specially designed components are inserted into pre-drilled holes either through heat installation or mechanical means, providing a durable threaded surface. Helicoil inserts are widely popular as they allow for strong internal threads in softer materials, significantly improving the durability of assembled products.

6. Anchors - Holding Firmly to Base Materials:

When fastening objects into base materials like concrete or masonry, anchors play a crucial role. They provide stability and reliability by creating secure connections even in challenging environments. Expansion anchors, chemical anchors, and screw anchors are commonly employed in construction projects that involve CNC machined components. The choice of anchor depends on factors such as load-bearing requirements, material properties, and environmental conditions.


Fasteners are an indispensable part of CNC machining applications, ensuring the seamless assembly of various components. Understanding the different types available, their unique features, and suitable applications allows companies to optimize their manufacturing processes while enhancing product quality and performance. From screws to rivets, each type of fastener contributes to the overall strength and functionality of the finished products. Therefore, it is essential to select the appropriate fasteners based on specific project requirements and consult with experts when necessary. CNC Milling
