    Characteristics of the flat washer by Cuong Thinh:

    • The flat washer 8.8 is typically distinguished into two surfaces, one smooth and one rough. The rough surface contacts the structure requiring connection, while the smoother surface contacts the stainless steel nut or the bolt head. Adhering to this specification prevents the washer from rotating during construction and avoids scratching the surface of the connecting structure.
    • Surface roughness and size tolerances comply with ISO 7089 or GB/T 3103 standards.
    • The dimensions of the flat washer 8.8 are manufactured according to standards and can also be customized based on drawing requirements.
    • The inner hole diameter dimensions are also produced according to standard specifications or can be customized based on the drawing requirements.

    Applications of the flat washer 8.8:

    It can be seen that the main task of the bolt is to ensure uniform distribution of the force transmitted from the static/dynamic load to the flat washer, the second most important task is to ensure that the tightening force on the bolt/nut does not destroy the wear and deformation of the equipment surface over time under the action of static/dynamic loads, and the third important task is to make maintenance easy.

    – For large-sized structures requiring connection, the washer can be used on both the lower and upper surfaces of the structure.

    – In cases where connections are prone to loosening over time, the flat washer is utilized in conjunction with domed washers, folded washers, or flange washers to prevent self-loosening of the joint.
