Learn to navigate the nuanced world of structural bolts with this comprehensive guide
07 Oct 2024

When it comes to construction and heavy engineering, the choice of a structural bolt plays a crucial role in ensuring the safety and reliability of your project. Regardless of the type of project you're working on, the selection of bolts can have a significant impact on the outcome. This guide will provide you with valuable insights into the important factors to consider when choosing structural bolts grades 8.8 and 10.9 along with the latest trends and innovations in this critical element of the construction world. We will also look at why Bigboltnut is making the headlines in the highly competitive structural bolts market globally.
 

What are structural bolts?

Structural bolts are specifically engineered fasteners intended to withstand the substantial pressures and stresses encountered in demanding construction projects. These bolts are commonly employed in steel-to-steel connections and must adhere to rigorous criteria for strength and longevity.

 

The A325 bolt and the A490 bolt are two frequently used variants of structural fasteners. The A325 bolt is a heavy hex bolt manufactured from medium-carbon steel that has been hardened and tempered to enhance its endurance. It is frequently employed in steel structures, providing a harmonious combination of robustness and adaptability. Conversely, the A490 bolt is crafted from alloy steel and undergoes heat treatment, resulting in increased tensile strength. As a result, it is well-suited for more challenging applications.
 

How do you choose the most suitable structural bolts?

Considering the following factors will help you make an informed decision when selecting structural bolts for your business:

 

  • Load requirements: It is important to ensure that the bolt's tensile strength is suitable for the load it will bear. When it comes to projects that demand the utmost strength, high-tensile bolts like the A490 are the perfect choice.
  • Environmental factors: Take into account the conditions of the surroundings where the bolts will be utilised. For instance, in certain locations, like coastal or industrial areas, it may be necessary to use bolts with coatings that are resistant to corrosion.
  • Standardisation: Make sure the bolts adhere to the necessary industry standards. As an example, both A325 and A490 bolts need to meet the standards set by ASTM (American Society for Testing and Materials).
     

Let’s look at the future trends

The structural bolt industry is constantly evolving, fuelled by the latest breakthroughs in materials science and manufacturing technology. Here are some significant trends that are shaping the future of structural bolts:

 

Advanced materials: Exciting advancements in materials have paved the way for the creation of bolts that are both lighter and stronger. These innovations, such as high-strength alloys and composite materials, are revolutionizing the industry. These materials provide enhanced resistance to corrosion and fatigue, significantly prolonging the lifespan of the bolts.

Improved manufacturing: The implementation of precision manufacturing techniques, such as CNC machining and robotic assembly, has resulted in structural bolts being produced with enhanced accuracy and consistency. This results in enhanced performance and dependability, especially in demanding situations.

Smart bolts: One of the most thrilling advancements in the field is the rise of "smart bolts." These bolts are equipped with sensors that constantly monitor tension and stress, providing engineers with valuable real-time data. This technology enables predictive maintenance, which minimises the chances of structural failures and enhances the longevity of the structure.

Environment consciousness: The demand for eco-friendly structural bolts is on the rise as the construction industry embraces more sustainable practices. This includes bolts made from recycled materials and those that can be easily disassembled and reused at the end of a structure's life.
