A square flat washer according to DIN 436 is a fastener for bolts or screws used primarily to provide uniform load distribution and to prevent the head of the screw or the nut from pressing through the material being joined. These washers are typically made of carbon steel, stainless steel or other non-ferrous metals and can be available in different finishes such as zinc, nickel or cadmium plated for improved corrosion resistance and aesthetics.
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:
Evenly Distribute Loads: Square flat washers provide a large contact area, which helps to evenly distribute loads applied by bolts or screws, reducing localized stresses. Prevents damage: The use of square flat washers prevents the surface of the connected material from being pressed through or scratched by the screw head or nut. Corrosion resistance: Especially square flat washers made of stainless steel have good corrosion resistance and are suitable for outdoor or humid environments. Various materials and surface treatments: Different materials and surface treatments can be selected according to different application requirements to suit different working environments.
Scope of Application
Construction industry: In building and civil engineering, square flat washers are used to connect beams, columns and other structural components, providing a stable and reliable connection. Machinery and equipment manufacturing: In machinery and equipment manufacturing, they are used to secure and adjust machine parts such as bearings, gears and motors. Chemical industry: In chemical plant construction, these 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, square flat washers are used to connect automotive components such as chassis and body fixings.
