high tensile bolts

High tensile bolts

High tensile bolts High tensile bolts made of high-strength steel, or bolts that require greater pre-tightening force, can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, 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 …
