Fasteners play an essential role in various industries, including CNC machining. These small yet mighty components are crucial for holding parts together with utmost precision and reliability. In this article, we will delve into the different types of fasteners used in CNC machining and shed light on their significance.

1. Bolts and Screws:
Bolts and screws are amongst the most commonly used fasteners in CNC machining. They secure two or more components by creating a threaded joint. Bolts have external threads with the head, while screws typically have internal threads without a head. Various materials such as stainless steel, carbon steel, and aluminum are utilized to produce these fasteners.

2. Nuts:
Nuts complement bolts and screws and are threaded internally to create a secure connection. CNC machines require different types of nuts, including hex, square, flange, and wing nuts. These nuts provide stability and enable easy disassembly when necessary.

3. Washers:
Washers are thin plates made from metal or plastic that distribute the load evenly across the fastened components. They prevent damage caused by friction between the fastener and the surface of the workpiece. Additionally, washers can act as locking devices, ensuring the fasteners remain tightened over time despite operational vibrations.

4. Rivets:
Rivets are permanent fasteners frequently used in structural applications of CNC machined parts. They feature a cylindrical shaft with a head at one end. During assembly, rivets are inserted into pre-drilled holes and then deformed to securely hold the components together using mechanical force or heat. Common types of rivets include solid, tubular, blind, and self-piercing.

5. Anchors:
Anchors are specialized fasteners employed when attaching objects to masonry, concrete, or other hard surfaces. They provide sturdy support by expanding or gripping the material once installed. Common types of anchors include sleeve, drop-in, wedge, and adhesive anchors. These fasteners are crucial when CNC machining involves mounting equipment or structures securely onto walls or floors.

6. Clips:
Clips are versatile fasteners that hold objects together without penetrating them with screws or bolts. They come in various forms such as spring clips, snap rings, and retaining rings. Clips are commonly used for securing bearings, gears, and other components within CNC machined assemblies.

7. Standoffs and Spacers:
Standoffs and spacers are indispensable for maintaining proper alignment between components during CNC machining. Standoffs elevate one component above another while spacers create precise gaps. These fasteners aid in heat dissipation, prevent short circuits, and provide electrical insulation if necessary.

8. Latches:
Latches are mechanisms used to secure doors, enclosures, and covers in CNC machined applications. They ensure that parts remain closed and locked, thereby safeguarding sensitive equipment from external factors like dust, moisture, and unauthorized access.


In the realm of CNC machining, fasteners fulfill a vital role in holding parts together reliably and precisely. From bolts and screws to rivets and latches, these diverse components play an essential part in ensuring the integrity and functionality of CNC-machined assemblies. By understanding the different types of fasteners available, manufacturers can select the most appropriate ones for their specific applications, guaranteeing quality, durability, and consistency in their products.
