CNC machining has revolutionized the manufacturing industry with its precision, efficiency, and versatility. From automotive parts to aerospace components, CNC machines play a crucial role in fabricating various products. One vital aspect of CNC machining is the use of fasteners, which ensure strong and secure connections between different parts. In this article, we will delve into the world of fasteners commonly employed in CNC machining.

1. Bolts:

Bolts are one of the most widely used types of fasteners in CNC machining. They come in different sizes, lengths, thread pitches, and grades, making them suitable for various applications. Bolts are typically tightened using hex nuts or threaded into pre-drilled holes using wrenches. Their structural integrity ensures adequate strength and resistance to applied forces.

2. Screws:

Screws are similar to bolts but have some distinguishing characteristics. While bolts often require nuts, screws usually feature external threads that allow them to be directly driven into tapped holes within assembled parts. The presence of a screwdriver slot or recessed head allows for easy tightening and removal. These versatile fasteners can be used in numerous industrial and household applications.

3. Nuts:

Nuts are essential companion pieces for bolts and screws. They come in multiple shapes and designs, the most common being hexagonal nuts. Hex nuts have six sides, enabling better grip and efficient torque application during installation. CNC machining facilitates the precise creation of threaded holes, ensuring optimal compatibility and interaction between bolts and nuts.

4. Washers:

Washers serve several purposes in CNC machining applications. Flat washers, for instance, distribute loads evenly while preventing damage to the connected surfaces. Lock washers effectively resist loosening caused by vibrations or constant motion. By providing necessary reinforcement and support, washers enhance the reliability and longevity of fastened connections.

5. Rivets:

Rivets are permanent fasteners commonly used in CNC machining to join two or more parts together. They consist of a cylindrical shaft with a head that can be solid, semi-tubular, or hollow. The riveting process involves driving the shaft through pre-drilled holes using hydraulic machinery, permanently deforming it on the backside using special tools called "rivet guns." Riveted connections ensure excellent strength and durability.

6. Threaded Inserts:

Threaded inserts are essential components when reinforcing threaded connections in CNC machining. Made from materials like steel, brass, or stainless steel, these inserts provide additional thread support when working with softer materials or repairing damaged threads. They are inserted into pre-drilled holes, creating secure and reliable tapped threads for bolts or screws.


Fasteners play a crucial role in achieving reliable and durable connections in CNC machining. From bolts and screws to nuts, washers, rivets, and threaded inserts, each type serves a specific purpose in ensuring structural integrity and functionality. Understanding the different types of fasteners and their applications allows manufacturers to choose the most suitable options for their CNC machining projects. With precision manufacturing techniques, including computer-controlled processes, the production of high-quality fasteners has become increasingly efficient, enabling seamless assembly and fabrication across various industries.
