Classification of high-strength bolts

2023-11-02

Friction type high-strength bolts: suitable for connecting steel frame beams and columns, solid web beam connections, heavy-duty crane beam connections in industrial buildings, brake systems, and important structures that bear dynamic loads. Pressure bearing high-strength bolts: can be used for shear connections in static load structures that allow for a small amount of sliding or components that indirectly bear dynamic loads. Tensile high-strength bolts: When the bolt is in tension, its fatigue strength is relatively low. Under dynamic load, its load-bearing capacity is not easy to exceed 0.6P (P is the allowable axial force of the bolt). Therefore, it is only suitable for use under static load, such as flange docking of compression members, T-joints, etc.
