Fasteners play a crucial role in the world of manufacturing, particularly in the realm of CNC machining. These small yet mighty components are essential for holding different parts together securely. The type of fastener used greatly influences the overall functionality and durability of a product. In this article, we will delve into the diverse types of fasteners commonly employed in CNC machining processes.

1. Screws:
Screws are one of the most ubiquitous fasteners utilized across various industries. With their threaded shafts and helical structures, they securely join two or more objects. Within CNC machining, screws are produced using precise techniques that include thread cutting, rolling, or extrusion. They come in numerous variations such as machine screws, set screws, self-tapping screws, wood screws, and more, each tailored to specific requirements.

2. Bolts:
Bolts resemble screws but differ in design and function. Instead of threading internally like screws, bolts have a smooth shaft with external threads. Their primary purpose is to provide strong and reliable connections through the use of nuts or tapped holes. CNC machining enables the production of a wide range of bolts, encompassing hex bolts, carriage bolts, anchor bolts, U-bolts, eye bolts, and others, catering to diverse applications.

3. Nuts:
Nuts complement bolts by providing the necessary counterpart for secure fastening. These small metal components feature an internal threaded hole matching the corresponding bolt size. Through CNC machining, a plethora of nuts can be manufactured, including square nuts, flange nuts, wing nuts, weld nuts, locknuts, and more. Precision machining ensures accurate dimensions, enabling proper engagement between nuts and bolts.

4. Washers:
Washers act as indispensable companions to screws, bolts, and nuts in CNC machining. Offering stability and distributing joint loads evenly, washers create more secure connections. CNC machining techniques allow for the production of various washer types, such as flat washers, lock washers, spring washers, and fender washers. These components are fabricated with precision to ensure optimal fit and performance.

5. Rivets:
Rivets serve a unique purpose by permanently joining materials together without requiring access from both sides. They consist of a cylindrical pin-like shaft that is inserted into pre-drilled holes and then compressed or hammered, causing the tail end to expand and create a strong connection. CNC machining processes produce different rivet styles, including solid rivets, blind rivets, drive rivets, and tubular rivets.

6. Clips:
Clips, also known as retaining clips or retaining rings, play an essential role in securing objects onto a shaft or within a groove. They exert inward pressure when installed, thereby preventing undesired movement or displacement. Common clip variations produced through CNC machining include snap rings, circlips, e-clips, and spiral retaining rings. These tiny yet significant fasteners find applications in machinery, automotive assemblies, and other industrial sectors.


In CNC machining, the type of fastener employed greatly influences the overall structural integrity and functionality of a product. Understanding the diverse array of fasteners available allows manufacturers to make informed decisions regarding their design and implementation. Whether it's screws, bolts, nuts, washers, rivets, or clips, each serves a specific purpose and provides solutions for countless manufacturing needs. With the accuracy and precision offered by CNC machining techniques, these fasteners can be fabricated to exact specifications, ensuring reliable and long-lasting connections throughout various industries.
