Exploring high strength bolts: differences in materials, strength and applications

As a common connecting element, bolts play an important role in various fields. In some special application scenarios, high strength bolt need to be used to meet higher requirements. So, what is the difference between high strength bolts and standard bolts? This article will unveil the mystery of high-strength bolts for you and provide an in-depth analysis from the aspects of materials, strength and applications.

Material differences

The most significant difference between high strength bolts and standard bolts is the choice of material. High strength bolts are usually made of alloy steel or stainless steel materials, which have higher strength and corrosion resistance. In comparison, standard bolts are typically made from regular carbon steel materials. The material selection of high-strength bolts allows them to perform better under greater loads and harsher environmental conditions.

difference in intensity

The naming of high strength bolts is often related to their strength levels, such as level 8.8, level 10.9, etc. These numbers represent the minimum tensile strength and minimum yield strength of the bolt. In comparison, standard bolts have a lower strength rating. High-strength bolts improve their strength through material selection and heat treatment to meet the needs of special application scenarios.

Application differences

Because high strength bolts have higher strength and corrosion resistance, they are widely used in fields with higher safety requirements. For example, in aerospace, automobile manufacturing, bridge construction and other fields, high strength bolts are often used to connect important structural parts to ensure their safety and reliability. Standard bolts are more commonly used in general mechanical equipment and construction fields.

There are obvious differences between high strength bolts and standard bolts in terms of materials, strength and applications. High-strength bolts are made of alloy steel or stainless steel, which have higher strength and corrosion resistance; they have a higher strength level and are enhanced by special processes; they are widely used in fields with high safety requirements. Understanding the characteristics and applications of high-strength bolts is of great significance for the correct selection and use of bolts.
