Class 8.8 High Strength Joint Bolts

The class 8.8 high strength joint bolts are made of medium carbon steel and undergo special quenching and tempering treatments. Their strength is much higher than that of ordinary bolts. Its screw has threads and can cooperate with the nut to tightly connect two or more components together.

Product applications

In the construction industry, class 8.8 high strength joint bolts are widely used. When building factories and Bridges, it should be used to connect the main load-bearing components such as steel beams and steel columns. For instance, when building the steel structure frame of a large factory, fixing the steel beams and columns with such bolts can ensure that the entire building structure remains stable over long-term use, withstanding wind, sun exposure, rain, and the vibrations generated by the operation of various equipment.

In the automotive manufacturing industry, class 8.8 high strength joint bolts are used. Just like the assembly of an engine, various parts need to be tightly connected to ensure that no component becomes loose when the engine is running at high speed. There is also the assembly of the car chassis. By connecting various components of the chassis with such bolts, the chassis can remain stable during driving, whether on flat or bumpy roads, ensuring driving safety.
