CNC machining has revolutionized the manufacturing industry, offering precision and efficiency in producing various components. Fasteners are essential mechanical devices used to join two or more objects together securely. From screws and bolts to nuts and washers, fasteners play a crucial role in numerous applications across industries. In this article, we will delve into the different types of fasteners used in CNC machining processes and discuss their importance.

1. Screws:
Screws are one of the most commonly used types of fasteners. They feature threaded bodies that allow them to engage with pre-threaded holes or create new threads. Screws come in diverse designs such as machine screws, self-tapping screws, and wood screws, catering to specific application requirements. CNC machines produce screws by cutting precise helical grooves on a cylindrical workpiece using rotating tools and controlled movements.

2. Bolts:
Bolts are similar to screws but have external threading along their entire length. They typically require a nut for proper installation. CNC machining facilitates the production of bolts with accurately cut threads, ensuring optimal fit and strength. Bolt-making involves turning operations on metal bars, followed by thread cutting or rolling processes.

3. Nuts:
Nuts are internally threaded components used in conjunction with bolts and screws to provide a secure joint. The CNC machining process ensures that the internal threads of nuts are meticulously created to meet desired specifications. Materials like steel, brass, and aluminum are commonly employed in nut production, enabling proper torque resistance and durability.

4. Washers:
Washers serve as spacers between fasteners and the surfaces they secure. They distribute the load evenly, prevent damage due to vibrations, and ensure tightness. CNC machining allows for the creation of washers with precise dimensions and thicknesses. These can be produced by punching or laser-cutting operations, which eliminate the need for post-machining.

5. Rivets:
Rivets are permanent fasteners used when welding or thread-based connections aren't feasible due to material limitations or tension conditions. CNC machines play a vital role in producing riveted joints by precisely drilling holes and inserting solid or tubular rivets into the hole, securing components together permanently.

6. Clips:
Clips are spring-like devices designed to hold objects together without screws or bolts. CNC machining processes enable the production of clips with intricate designs and precise dimensions. Various materials like stainless steel, plastic, or carbon fiber can be used depending on the specific application requirements.

7. Anchors:
Anchors provide support and stability when fastening objects to different surfaces such as concrete or drywall. CNC machines aid in manufacturing anchors capable of securely holding heavy loads. Through controlled cutting, shaping, and milling operations, these fasteners offer reliable attachment points for various fixtures.


In CNC machining, the production of high-quality fasteners is essential to ensure proper assembly and functionality of countless products across industries. From simple screws to complex clips and anchors, the precision and versatility offered by CNC machines have revolutionized fastener manufacturing. By understanding the different types of fasteners available, manufacturers can choose the ideal options for their specific applications, ensuring strong and durable connections. The reliability and accuracy provided by CNC machining continue to drive advancements in fastener technology, contributing to efficient and innovative manufacturing processes worldwide. CNC Milling
