In the world of CNC machining, fasteners play a crucial role in securely joining components together. Through their wide range of designs and applications, they ensure structural integrity, functionality, and efficiency throughout various industries. In this article, we delve into the different types of fasteners commonly used in CNC machining processes and explore their unique characteristics.

1. Bolts:
Bolts are one of the most popular types of fasteners used in CNC machining. They consist of a threaded shaft with an external head, typically hexagonal or square-shaped. Bolts provide robust strength and can be easily tightened using a corresponding nut. Common examples include machine bolts, shoulder bolts, and carriage bolts. Their versatility makes them suitable for numerous applications such as automotive manufacturing, construction, and aerospace industries.

2. Screws:
Screws differ from bolts primarily based on their purpose. Unlike bolts that require nuts, screws can create their own mating threads within the base material. This characteristic allows them to provide a secure hold without the need for additional hardware. CNC machines use screws extensively due to their ease of use and reliable holding power. The most commonly used screws in CNC machining are wood screws, self-tapping screws, and machine screws. These versatile fasteners find applications in furniture assembly, electronics, and machinery fabrication.

3. Nuts:
Nuts are essential fasteners used in conjunction with bolts, providing a means to secure two or more parts together. They usually have a threaded interior surface that mates with the external threading of the bolt. Variations in shapes and designs allow for specific application requirements. Hex nuts, wing nuts, and locknuts are some common examples utilized in CNC machining. Nuts serve as vital connecting elements in automotive manufacturing, engineering, and appliance production.

4. Washers:
Washers are flat, disc-like fasteners with a hole in the center. They are positioned between bolts or nuts and the surface of the material being fastened. Washers distribute the load, prevent damage to the workpiece, and provide stability by creating a smooth mating surface. Their types include flat washers, spring washers, and lock washers. In CNC machining processes, washers often find use in automotive assembly lines, sheet metal fabrication, and electrical equipment manufacturing.

5. Rivets:
Rivets offer permanent joining solutions without the need for any external threading or hardware. These mechanical fasteners consist of a cylindrical shaft with a head on one end that expands upon installation, securely fixing two materials together. Commonly used in aircraft manufacturing, rivets can withstand high vibrations and shear forces. Types of rivets include solid, blind, and tubular rivets, each tailored for specific applications where reliability and durability are crucial.

6. Anchors:
Anchors are fasteners designed to secure objects to surfaces where traditional screws or bolts cannot be used effectively. They anchor themselves within the base material using various mechanisms such as expansion, adhesive bonding, or friction fitting. Popular examples include concrete anchors, wall anchors, and drywall anchors. Anchors find extensive application in construction projects, furniture installations, and hanging heavy objects.


Understanding the different types of fasteners utilized in CNC machining is essential for ensuring reliable connections and structural integrity across various industries. Bolts, screws, nuts, washers, rivets, and anchors all contribute to the efficient assembly of components through their unique designs and characteristics. By selecting the right type of fastener based on specific application requirements, manufacturers can achieve superior performance, longevity, and safety in CNC machined products.
