CNC machining is a revolutionary manufacturing process that utilizes computer-controlled machines to produce intricate and precise parts. One crucial aspect of this process is the use of fasteners, which ensure the strength, durability, and functionality of the final products. In this article, we will explore the various types of fasteners used in CNC machining and discuss their applications.

1. Bolts and Screws:

Bolts and screws are undoubtedly the most common types of fasteners used in CNC machining. These versatile fasteners come in different sizes, shapes, and materials to suit specific requirements. Bolts are typically larger and feature external threading, while screws have smaller diameters and internal threading. They are primarily used to secure two or more components together and provide structural integrity.

2. Nuts:

Nuts are companion fasteners to bolts and screws. They are designed with internal threading to engage with the external threads of the aforementioned fasteners. Nuts serve multiple purposes within CNC machining applications - they can distribute load, provide tight connections, and prevent loosening due to vibrations over time.

3. Washers:

Washers are small, flat discs often placed between the fastener and the material being fastened. They act as spacers, protectors, and even tension devices. There are several types of washers, including plain washers (standard), spring washers (provide preload for tighter connections), and lock washers (prevent loosening).

4. Rivets:

Rivets are permanent fasteners extensively used in CNC machining. They consist of a shaft and a head and are secured by deforming or upsetting the unexpanded end after insertion into pre-drilled holes. Rivets offer high reliability, shear strength, and resistance to vibration, making them ideal for robust assemblies.

5. Pins:

Pins play a vital role in alignment and joining of various components in CNC machining. They are typically cylindrical and can be either straight or tapered. Pins ensure accurate positioning, prevent movement between parts, and enable easy disassembly for maintenance or repair purposes.

6. Anchors:

Anchors are fasteners designed to provide secure attachment points within materials like concrete, brick, or stone. Used extensively in construction projects, anchors come in various types such as wedge anchors, sleeve anchors, and drop-in anchors. In CNC machining, anchors are commonly used when attaching machine bases to a stable surface.

7. Clips and Clamps:

Clips and clamps are versatile fastening devices widely employed in CNC machining. They offer ease of installation, adjustment, and removal without causing any damage to the underlying material. Clips are usually used to hold wires or cables neatly, while clamps create temporary joints or provide gripping force during machining processes.

8. Studs:

Studs are threaded rods that do not have heads and project at each end. They serve as anchor points for other fasteners or mating components. Studs are often used to attach flanges, mount machinery, or secure heavy-duty applications where removable connections are necessary.

9. Adhesive Fasteners:

Adhesive fasteners include tapes, glue, epoxy, and other bonding agents. While they may not be traditional mechanical fasteners, their ability to securely join materials in CNC machining cannot be overlooked. Adhesive fasteners eliminate the need for drilling holes, reducing stress concentrations and potential weaknesses on delicate components.


In the dynamic world of CNC machining, understanding the different types of fasteners is essential for producing high-quality, reliable, and durable products. From bolts and screws to rivets and adhesive fasteners, each type has unique characteristics to fulfill specific design requirements. By choosing the right fastener, manufacturers can ensure successful assembly and optimize the performance of complex CNC-machined parts. CNC Milling
