When the bolts need to be disassembled frequently, to protect the surface of the connected part from being scratched, it is generally necessary to place a flat washer at the position of the nut or bolt head, to prevent the surface of the connected part from being scratched.
In some joints with friction coefficient requirements, such as high-strength prestressed bolts, a flat industrial gasket is required at the nut end. In this case, the bolt, nut, and industrial gasket are all provided by the same manufacturer. The bolt manufacturer needs to The nut and the industrial gasket is treated accordingly to ensure that the coefficient of friction between the nut and the industrial gasket remains consistent.
When the bolt strength is relatively high and the allowable compressive stress of the connected parts is relatively low, to reduce the compressive stress of the pressure-bearing surface of the connected parts, it is generally necessary to increase a flat industrial gasket.
In bolt connection, the pressure transmission of the bearing surface of the bolt head or nut gradually expands in a flared shape. The larger the bearing surface, the smaller the compressive stress. Therefore, the addition of a flat industrial gasket can reduce the compressive stress of the contact surface of the connected part. , To ensure the effectiveness of the bolt connection.
