DIN6340 Washer/Heavy Washer, M6-M30, Plain/Dacromet

Standard:DIN6340

Description:

The DIN 6340 standard specifies heavy washers used in structural applications. The parameters you mentioned, M6-M30, indicate that these washers are available in metric sizes ranging from M6 to M30.

The "Plain" and "Dacromet" coatings are two different types of surface finishes that can be applied to these washers:

1.Plain: Plain washers refer to washers without any additional coating or finish. They are typically made of carbon steel and do not have any corrosion protection. Plain washers are suitable for use in indoor or dry environments where corrosion is not a concern. If used in outdoor or corrosive environments, they may rust over time.

2.Dacromet: Dacromet is a brand name for a type of coating that provides excellent corrosion resistance. It is a thin, inorganic coating that is applied to the surface of the washers through a dip-spin process. Dacromet coatings offer high resistance to corrosion, salt spray, and various chemicals. These coatings are commonly used in applications where washers are exposed to harsh environments or where long-term corrosion protection is required.

In summary, DIN 6340 heavy washers are available in metric sizes ranging from M6 to M30. They can be obtained with either a plain finish, which provides no corrosion protection, or a Dacromet coating, which offers excellent corrosion resistance. The choice of coating depends on the specific application and the level of corrosion protection required.
