Fasteners play a crucial role in various industries, especially in CNC machining. Whether you are an industry professional or simply someone with curiosity about different types of fasteners used in this field, this article aims to provide a comprehensive guide to help you understand their significance and applications.

1. Nuts:
Nuts are among the most common types of fasteners used in CNC machining. These small yet mighty components secure bolts, screws, or studs in place by creating a threaded connection. There is a wide variety of nuts available, including hex nuts, nylon lock nuts, wing nuts, and more. Each nut has its specific purpose and suits different applications depending on factors like load-bearing requirements, accessibility, and torque resistance.

2. Bolts:
Bolts are essential components that complement nuts in establishing strong connections. Usually made from steel, stainless steel, or titanium, bolts feature external male threads while being screwed into nuts. They come in various types such as hex bolts, shoulder bolts, carriage bolts, and eye bolts. The choice of bolt depends on factors like strength, corrosion resistance, size, and intended use/application.

3. Screws:
Similar to bolts, screws are internally threaded fasteners designed to hold objects together or attach them to a surface. The key difference between bolts and screws lies in their application. While bolts require nuts for proper functionality, screws can penetrate materials directly without additional hardware. Common screw variations include wood screws, machine screws, self-tapping screws, and sheet metal screws.

4. Rivets:
Rivets are permanent fasteners widely used in CNC machining for joining two or more pieces of material together. This type of fastener features a solid shank and a head and is secured by deforming its tail-end called "head formation." Popular rivet options include solid rivets, blind rivets, tubular rivets, and drive rivets. Riveted joints provide excellent strength and are used extensively in automotive, aerospace, and structural applications.

5. Washers:
Washers play a significant role in ensuring fastener integrity and protecting surfaces from damage caused by tightening forces. These thin metal or plastic discs distribute the load evenly across the surface while preventing nuts, bolts, or screws from loosening due to vibrations. Common washer types include flat washers, spring washers, lock washers, and fender washers. Choosing the right washer enhances the fastener's stability and longevity.

6. Clips and Clamps:
In CNC machining, clips and clamps are essential for holding components securely in place during cutting, shaping, or assembly processes. They not only provide stability but also enable easy repositioning when needed. Spring clips, retaining rings, wire forms, hose clamps, and circlips are commonly utilized to secure various parts effectively, minimizing any risks of misalignment or dislocation.


CNC machining heavily relies on the utilization of different types of fasteners to ensure efficient operations, precise alignments, and durable connections. From nuts and bolts to screws and rivets, each fastener has its unique purpose and contributes to maintaining the structural and functional integrity of assembled components. Understanding the diverse range of fasteners enables industry professionals to choose the most suitable options based on material compatibility, load requirements, accessibility, corrosion resistance, and other crucial factors. By mastering the art of selecting and implementing fasteners, CNC machining industries can achieve enhanced productivity, reliability, and successful project outcomes. CNC Milling CNC Machining
