Choosing the Right Pressure Bolt: Material and Size Considerations

When installing machinery or equipment, one of the most important factors to consider is the type of fasteners you use. Pressure bolts are among the most popular fasteners that engineers and manufacturers rely on. Pressure bolts join various load-bearing parts of a machine or equipment with a tight grip, ensuring they remain in place even under heavy vibrations or dynamic loads.

In this blog post, we’ll discuss why choosing the right type of pressure bolt is essential, the various materials and sizes available for pressure bolts, and tips on selecting the right pressure bolt for your project. By the end of this post, you’ll understand which type of pressure bolt you need to get the job done right.

Choosing the Right Pressure Bolt: Material and Size Considerations

Material Considerations:

One of the key considerations when selecting a pressure bolt is the material. Stainless steel pressure bolts are popular in industrial settings because they can endure harsh environments and resist corrosion and other forms of wear and tear. Other metals used for pressure bolts include alloy, carbon steel, and titanium. The choice of material will depend on the specific application of the pressure bolt; choosing a material that matches the expected environmental and mechanical demands will ensure the pressure bolt does its job well.

Size Considerations:

The right size pressure bolt depends on your specific application and the size of the load that the pressure bolt needs to bear. The most common sizes of tension control bolts are M16, M20, and M24. Another critical factor to remember when selecting a pressure bolt is the tension needed to securely fasten the components. Therefore, it is essential to use an appropriate bolt tension measuring tool to ensure that the tension bolt is tightened to the recommended torque.

Types of Pressure Bolts:

After figuring out the size and material, you now have to consider the type of pressure bolt. The most common types include hexagon socket heads, heavy hexagon, square, round, and countersunk heads. The shape of the bolt head will affect the tightening tool required and the potential for corrosion or other forms of wear, so it is crucial to understand the specific differences between these bolt head types when selecting a pressure bolt for a project.

Selecting the Right Pressure Bolt:

Now that you know the critical factors when selecting pressure bolts, the next question is, how do you choose the right one for your specific project? The most important thing is to know the project’s specific requirements, including the expected environmental factors, load size, and load capacity. Of course, feel free to consult with specialists or suppliers for expert advice if required. Properly specifying these variables can help you choose the ideal material and size of the pressure bolt required, along with its head type, allowing your fasteners to perform as intended.


Choosing the right pressure bolt depends on many factors, including the material and size of the bolt and the application’s specific requirements. As a general rule, ensure that you choose bolts that can handle the necessary load and environmental factors where they are required. Ultimately, selecting the right pressure bolt can result in better and safer operation of the machine or equipment. Regardless of your specific project requirements, finding the right supplier for your pressure bolts can ensure you get the best and most innovative options to select from that precisely match your needs.
