GB97 and DIN125 standard flat washers are a commonly used fasteners, mainly used with bolts, screws or nuts to increase the contact area of the locked parts and disperse the pressure, reduce the friction between the bolt and the locked parts, to protect the surface of the locked parts from wear and tear, and at the same time, to a certain extent, play a role in preventing loosening.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Increased contact area: By increasing the contact area, flat washers help to spread the pressure exerted by the fastener and prevent damage to the connected part. Reduces friction: The use of flat washers reduces direct friction between the bolt or screw and the connected part, extending the life of the fastener. Anti-loosening properties: To a certain extent, flat washers can prevent the bolt or nut from loosening due to vibration. Material diversity: flat washers can be made of different materials such as carbon steel, stainless steel, non-ferrous metals and even plastics to meet different application environments and corrosion resistance needs. Variety of surface treatments: Flat washers can be electro-galvanized, environmentally friendly galvanized, hot-dipped galvanized, copper nickel-plated and other surface treatments to improve corrosion resistance and aesthetics. Uniform standards: GB97 and DIN125 standards provide uniform specifications for the dimensions and tolerances of flat washers, ensuring compatibility with other fasteners.

Scope of Application

Machine construction: In machine and equipment construction, flat washers are used to secure and adjust machine components such as bearings, gears and motors. Construction industry: In building and civil engineering, they are used to connect beams, columns and other structural components, providing a stable and reliable connection. Chemical industry: In the construction of chemical plants, flat washers are used to connect and secure equipment such as pipes, pressure vessels and heat exchangers due to their good corrosion resistance. Automotive industry: In automotive manufacturing, they are used to connect automotive components such as chassis and body fixings. Electronic industry: In electronic equipment, flat washers can be used to ensure good electrical contact while providing some sealing.
