In the world of CNC machining, fasteners play a crucial role in assembling and securing various components. Whether you are an engineer, mechanic, or even DIY enthusiast, having a sound knowledge of different types of fasteners is essential as it ensures the integrity and strength of your creations. From screws to rivets, bolts to nuts, let's explore the diverse range of fasteners extensively used in CNC machining.

1. Screws:
Screws are perhaps the most common and widely used type of fastener in CNC machining. They come in different sizes, materials, head shapes, and thread patterns. The choice of screws depends on factors like load-bearing capacity, resistance to corrosion, and aesthetic requirements. Metal screws with threaded shafts are typically drilled into pre-tapped holes using specialized tools or inserted through smooth holes along with accompanying nuts.

2. Bolts:
Similar to screws, bolts are externally threaded fasteners primarily employed for joining heavy-duty components. Unlike screws, bolts require corresponding nuts to hold them firmly together. With their varying structural designs, such as hexagonal heads and countersunk heads, bolts offer versatility when it comes to applications in CNC machining.

3. Nuts:
Nuts are internally threaded fasteners that complement bolts or threaded rods. CNC machinists utilize different types of nuts ranging from regular hexagon-shaped to square and wing nuts. These enable secure connections, allowing for adjustment and disassembly based on specific project requirements.

4. Washers:
Washers are often overlooked but nonetheless indispensable in CNC machining. Acting as effective load distributors, washers prevent damage to surfaces, enhance stability, and reduce friction between fasteners and connected components. Flat washers, spring washers, and lock washers are some commonly used varieties.

5. Rivets:
Rivets are permanent fasteners frequently used in structural applications. They consist of a pin-like body and a formed head, generally created by hammering or compression techniques. The process of riveting involves drilling holes, inserting the rivet, and deforming its end to secure the joint. CNC machining utilizes various rivet types, including solid, blind, tubular, and explosive.

6. Clips:
Clips provide fast and readily detachable connections in CNC machined assemblies. These small, spring-loaded components are designed to grip onto surfaces firmly. Clips find extensive use in industries such as automotive, aerospace, and electronics to hold cables, wires, panels, or covers securely.

7. Anchors:
In cases where you need to attach components or fasteners to materials like concrete, anchors come to the rescue. Widely used in construction projects and CNC machining applications, they offer stability and strength in demanding environments. Wall anchors, expansion anchors, and sleeve anchors are essential examples in this category.


CNC machining relies heavily on a wide variety of fasteners to create durable and reliable products. Understanding the different types of fasteners allows engineers, hobbyists, and machine operators to make informed choices when it comes to material selection, load-bearing capacities, and assembly techniques. By choosing appropriate fasteners, one can ensure that their creations possess structural integrity and longevity. To excel in CNC machining, mastering the art of fastener usage is an essential skill no one in the field should overlook. CNC Milling CNC Machining
