Application Of China Stud Supplier Gasket

  • When a high-strength nut is connected, the washer is essential, so what role can the washer play? Today, let’s take a look at this little partner with China Stud Supplier!
    1. When the bolts need to be disassembled frequently, in order 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, so as to prevent the surface of the connected part from being scratched.
    2. In some joints where the coefficient of friction is required to be more accurate, such as high-strength prestressed bolts, flat washers are required at the nut end, because in this case bolts, nuts, and washers are provided by the same manufacturer. The bolt manufacturer The nut and washer need to be treated accordingly to ensure that the coefficient of friction between the nut and the washer remains consistent.
    3. When the bolt strength is relatively high and the allowable compressive stress of the connected part is relatively low, in order to reduce the compressive stress of the pressure-bearing surface of the connected part, it is generally necessary to add a flat washer.

    1. In the bolt connection, the pressure transmission of the pressure bearing surface of the bolt head or nut gradually expands in a trumpet shape. The larger the pressure bearing surface, the smaller the compressive stress. Therefore, the addition of a flat washer can reduce the pressure on the contact surface of the connected part. Stress to ensure the effectiveness of the bolt connection.
      5. In some occasions, in order to ensure the one-to-one correspondence between the bolt holes between the two connectors, we need to increase the diameter of the hole to compensate for the deviation of the hole position. When the bolt hole exceeds the standard requirement, it is necessary to add a flat washer.
      6. Sometimes for the convenience of installation and adjustment, the Hexagon Socket Head Bolt hole will be made into a long hole, so that the installation position of the workpiece can be adjusted within a certain range. When a long hole is used, a thicker flat washer must be used. Special washers or multiple washers.
