Bolts made of high-strength steel, or bolts that require a larger pre-tightening force, can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, steel rails, high-pressure and ultra-high-pressure equipment. The fracture of this kind of bolt is mostly brittle fracture. High-strength bolts applied to ultra-high pressure equipment need to be pre-stressed in order to ensure the sealing of the container.
