DIN6916 Plain Washer M12-M36 Plain/Dacromet Structural Washers
Standard:DIN6916
Description:
DIN 6916 washers, also known as structural washers or heavy-duty washers, are specified by the DIN 6916 standard. They are used in structural applications to provide a larger bearing surface and distribute the load when used with bolts or screws. The size range you mentioned, M6 to M30, refers to the metric diameter of the bolt or screw they are designed to work with.
DIN 6916 washers are characterized by their specific dimensions, size, and thickness, which are standardized according to the DIN specifications.
DIN 6916 flat steel washers are commonly used in construction, steel fabrication, and industrial applications where high-strength connections are essential.

Plain finish:
Plain washers have no additional coating or finish applied to them. They are typically made of carbon steel and do not provide corrosion resistance. Plain washers are commonly used in indoor or dry environments where exposure to moisture or corrosive elements is limited. However, they may rust over time if subjected to moisture or harsh conditions.
Dacromet finish:
Dacromet is a brand name for a type of coating that offers excellent corrosion resistance. It is an inorganic coating applied to the surface of the washer through a dip-spin process. Dacromet coatings provide a high level of protection against corrosion, salt spray, and various chemicals. They are commonly used in applications where washers are exposed to harsh environments or where long-term corrosion protection is required.
