The GB93 and DIN127 standards deal with spring washers, which are mainly used on bolts or screws to provide extra clamping force and prevent loosening.The GB93 standard refers to spring washers in the Chinese national standard, while DIN127 is the German industrial standard for spring washers.

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:

Corrosion Resistance: The white washed zinc treatment improves the corrosion resistance of the washers, especially in wet or chemical environments. Aesthetics: This treatment gives the washer a uniform and aesthetically pleasing white appearance for applications where aesthetics are important. Increased service life: The whitewashed zinc treatment creates a protective film on the surface of the washer, extending its service life. Multiple Material Options: In addition to carbon steel, these washers can also be made from stainless steel or other alloys to suit different applications.

Scope of Application

Machinery and equipment manufacturing: In machinery and equipment manufacturing, for fixing and adjusting machine parts such as bearings, gears and motors. Building and civil engineering: in building and civil engineering, for connecting beams, columns and other structural components, providing stable and reliable connections. Automotive industry: In automotive manufacturing, for connecting automotive components such as chassis and body fixings. Chemical industry: In the construction of chemical plants, these washers are used to connect and secure equipment such as pipes, pressure vessels and heat exchangers due to their good corrosion resistance.
