Features:

The flat washer is produced based on the DIN125 standard. It is a flat metal ring with dimensions that conform to the DIN125 standard, which makes it easy to place between parts that need to be connected and has a wide range of applications.
Using flat washers can effectively distribute the pressure generated by nuts on connecting parts and prevent mechanical systems from being damaged due to excessive pressure.
Using flat washers can increase the contact area between the nut and the connected parts, improve the stability, safety and reliability of the mechanical system, and extend its service life.
These washers have good elasticity and wear resistance. They are usually made of spring steel, such as 65Mn, and then undergo oxidation treatment and heat treatment to achieve a hardness of 44-51HRC.

Advantages:

Strong Universality: The DIN 125 Flat Washer is a standardized product that can be widely used in various mechanical equipment and projects, offering high universality.
Easy Installation: Due to its flat shape and simple structure, the DIN 125 Flat Washer is easy to install and remove, reducing maintenance costs and time.
Improved Connection Reliability: By distributing pressure and enlarging the contact area, the DIN 125 Flat Washer significantly improves the stability and reliability of connections, reducing the possibility of failures and accidents.

Applications:

Mechanical Equipment: The DIN 125 Flat Washer is widely used in various mechanical equipment, such as automobiles, ships, aerospace, and construction, for connecting and fixing various components.
Fastener Connections: These washers are often used along with bolts, screws, and other fasteners to provide additional support and protection, ensuring secure and reliable connections.
Piping Systems: In piping systems, the DIN 125 Flat Washer can be used to connect pipes, valves, and other components, preventing leaks and damage.
