What is an HS bolt?

HS bolt, comes from its full name high strength bolt, which are high strength bolts made from carbon steel or alloy steel, with quenched-tempered heat treatment. High strength bolts are usually grade 8.8, 10.9, 12.9. Among these, grade 10.9, HDG are the most common seen in the market.

What is the difference between a normal bolt and a high strength bolt?

The difference between a normal bolt and a high strength bolt lie in their material grade and manufacturing process. Normal bolts are usually made from low carbon steel and no need to be tempered heat treament, say grade 4.8, 5.8, while high strength bolts are high tensile bolts grade 8.8, 10.9, 12.9, A325, A490 etc. Ningbo Fastenwell as one of the leading high strength bolts manufatcurer in Ningbo, HS bolts grade 8.8 and 10.9, hot dip galvanized are our main products in regular manufacturing and exporting, especially for construction projects.

Whether it be roads, buildings, bridges or other structures, a high strength bolt is a vital component in the strength and durability of any infrastructure. They are manufactured to withstand extreme forces, pressures and loads, and the materials producing high strength bolts are carefully selected for their ability to withstand extreme forces and stresses. For example, many high strength bolts are made from alloy steel that are specifically formulated to provide exceptional strength and hardness. Additionally, the bolts are often heat treated to further enhance their properties and performance allowing them to withstand bending, shearing and other types of stress without breaking or deforming.


High strength bolts are commonly used to connect steel girders in bridge construction, where he bolts must support the weight of heavy vehicles and withstand the forces of wind and other environmental factors.

Another advantage of high strength bolts is their ability to enhance the lifespan of infrastructure. These bolts can withstand harsh weather conditions, earthquakes and other natural disasters that have the potential to destroy infrastructure that isn't properly built. They can also maintain their strength in corrosive environments, so they don't rust or deteriorate over time.

In addition to their strength and durability, high strength bolts also offer several advantages in terms of installation and maintenance. These bolts are typically installed using torque wrenches, which ensure that the bolts are tightened to the precise specifications required for optimal performance. In some cases, high strength bolts may also be designed for easy removal and replacement, allowing for easier maintenance and repairs.

So whether you in bridge construction, building design, or other applications like large scale structures, high strength bolts play a crucial role ensuring the safety and stability of your project.
