Product Description



      DIN 6340 washers, also known as plain washers, are specified by the DIN 6340 standard. They are used to distribute the load and provide a larger bearing surface 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.

      When it comes to surface finishes for DIN 6340 washers, two common options are plain and Dacromet. Let's explore each of these finishes:

      1.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.

      2.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.

      The choice between plain and Dacromet finishes depends on the specific application requirements, considering factors such as the operating environment and the desired level of corrosion protection. Dacromet-coated washers are typically preferred for outdoor or highly corrosive environments where enhanced protection is crucial. Plain washers may be suitable for less demanding indoor or dry applications where corrosion resistance is not a significant concern.
