The high-strength bolt is made of high-strength steel and requires a large pre tightening force. There are several categories as follows.
Friction type is applicable to beam and column connection, solid web beam connection and factory heavy lifting beam connection
Pressure bearing high-strength bolts are suitable for shear connections of static load structures that allow less sliding.
When the tensile bolt is in tension, its fatigue strength is relatively low, so it can only be used for flange butt joint of pressure bar.
Thread: coarse, fine
Material: Carbon steel
Grade: 4.8 6.8 8.8 10.9 12.9
Standard: DIN GB ISO JIS ANSI
Used: building industry machinery

During the use of high-strength bolts, the floating rust, oil stain on the surface, burr and welding tumor on the bolt hole wall shall be removed.
The treated contact friction surface shall meet the specified anti scratch coefficient. It shall be equipped with corresponding nuts and washers, which shall be used together and shall not be interchangeable.
During installation, the treated friction surface of components shall not be stained with oil, dust and other sundries.
High strength bolts are widely used in machinery industry, automobile industry, construction industry, railway, electronics industry, power plants and so on.
