DIN9021 Heavy Plain Dacromet Washer M6-M100 for Construction
Description of DIN 9021 Flat Steel Washer:
Plain washers have no additional coating or finish applied to them. They are typically made of carbon steel and do not provide corrosion resistance. These washers are suitable for use in indoor or dry environments where corrosion is not a concern. However, they may rust over time if exposed to moisture or corrosive elements.
DIN 9021 washers typically have a plain finish, but they can also be available with coatings like zinc plating or other corrosion-resistant finishes for enhanced durability in different environments.
DIN 9021 washers are widely used in construction, automotive, and various other industries where secure fastening and load distribution are essential. The choice between plain and Dacromet finishes depends on the specific application requirements, including the level of corrosion resistance needed.
