CNC machining has revolutionized the way we manufacture products by utilizing computer-controlled machines to produce precise and complex components. The process involves a wide range of tools, techniques, and materials, with fasteners being an essential component in ensuring structural integrity and functionality. In this article, we will delve into the world of CNC machining and explore the different types of fasteners commonly used.

1. Screws:
Screws are ubiquitous fasteners utilized in nearly every industry and application. In CNC machining, they play a crucial role in securing various components together. CNC screws come in different forms such as machine screws, self-tapping screws, and set screws. Machine screws typically have a flat or pan-shaped head, and their threaded shafts allow them to be inserted into pre-drilled holes, providing excellent holding power. Self-tapping screws have sharp threads that cut through the material, making it ideal for joining disparate materials. Set screws lack a head and instead feature a shaped tip designed to sit flush within a drilled hole or against another surface.

2. Bolts and Nuts:
Bolts and nuts form the backbone of most mechanical assemblies. These threaded fasteners provide strong and reliable connections, allowing disassembly and reassembly whenever necessary. With CNC machining, bolts can be produced in a myriad of shapes and sizes, including hexagonal, square-headed, and countersunk variations. Nuts, on the other hand, serve as the counterpart to bolts and are available in numerous styles, such as wing nuts and locknuts. Together, bolts and nuts offer versatility and flexibility in CNC manufacturing processes.

3. Rivets:
Rivets are permanent fasteners used when welding or using screws is not suitable. These cylindrical pins maintain integrity by creating a robust connection between two separate parts. In CNC machining, rivets are often produced from metals like aluminum, brass, or stainless steel. The process involves using tools to deform and expand one end of the rivet while compressing it against the other material firmly.

4. Anchors:
Anchors are fasteners designed to create a secure connection between objects and base materials that may not necessarily have adequate strength on their own. CNC machining allows for the fabrication of various types of anchoring mechanisms such as wedge anchors, sleeve anchors, and expansion anchors. Depending on the application, these fasteners can be used in concrete, masonry, drywall, and even wood.

5. Clips and Clamps:
Clips and clamps are essential in holding pieces together during the CNC machining process to ensure accuracy and precision. These fasteners encompass a wide array of options, including spring clips, hose clamps, C-clamps, and quick-release couplers. CNC machined clips and clamps provide robust gripping power while allowing easy adjustment or removal when necessary.


CNC machining offers limitless possibilities, enabling the production of intricate components and structures. Fasteners play a vital role in ensuring the integrity and functionality of these products. Understanding the different types of fasteners available in CNC machining - screws, bolts and nuts, rivets, anchors, and clips/clamps - helps designers, engineers, and manufacturers choose the most suitable option for their specific applications. By utilizing fasteners strategically, CNC machining unlocks new levels of efficiency, durability, and quality in the manufacturing industry. CNC Milling
