As the professional manufacturer in China, Jiaxing aoke would like to provide you DIN7980 spring washers. You can rest assured to buy lock washers from our factory. DIN7980 spring lock washer is the German Industrial Standard for "Spring Washers for Cylinder Head Screws." Compared to the commonly used DIN127 spring washers, DIN7980 spring washers have a smaller outer diameter and are specifically designed for use with DIN 912 hexagon socket head screws. Why are we choosing stainless steel to produce DIN7980 spring lock washers? Stainless steel 304 (A2)/316 (A4) stainless steel offers corrosion resistance levels that cover atmospheric, freshwater, mild acid and alkaline, and marine environments. Stainless steel DIN7980 spring washers have a bright surface, require no electroplating, eliminate the risk of hydrogen embrittlement, and are RoHS/REACH compliant.
Jiaxing Aoke warmly welcome you to wholesale DIN7980 spring washers from our factory. We have a large amount of factory inventory. DIN7980 spring washers are specifically designed to prevent loosening of DIN912 hexagon socket head screws. Compared to DIN127 spring washers, DIN7980 washers have a smaller outer diameter. AOKE manufactures DIN7980 washers with precise dimensions, maintaining tight tolerances for outer diameter and thickness. When the bolt is tightened, the DIN7980 spring washer is compressed, generating a continuous axial spring force that offsets the loss of bolt preload due to vibration and temperature fluctuations. Stainless steel A2 DIN7980 spring lock washers are used in humid environments and outdoor equipment. For highly corrosive environments (such as coastal areas and chemical plants), 316L DIN7980 lock washers are recommended. They contain 2%-3% molybdenum and are resistant to long-term corrosion from seawater and weak acids.
