Standard:DIN6916
Description:
The DIN 6916 washer, also known as a structural steel washer, is a type of washer that conforms to the DIN 6916 standard. These washers are commonly used in construction, engineering, and industrial applications where high load-bearing capacity and durability are required.
The M12-M36 size range indicates that these washers are suitable for use with bolts or threaded fasteners ranging from M12 to M36 in diameter.
Regarding the surface finishes available for DIN 6916 washers, they can come in two options: plain and Dacromet.
Plain washers refer to washers without any additional surface treatment. They are made of plain steel and do not have any specific coating or finish applied to them. Plain washers are suitable for applications where corrosion resistance is not a primary concern or where additional measures are taken to protect against corrosion.
Dacromet is a type of surface coating that provides excellent corrosion resistance. It is a thin, organic coating that is applied to the washer's surface through a dip-spin process. Dacromet coatings offer high-performance corrosion protection, even in harsh environments or exposure to chemicals, making them suitable for applications requiring superior resistance to rust and corrosion.
The choice between plain and Dacromet finishes depends on the specific requirements of the application, including the level of corrosion resistance needed and the operating conditions the washer will be subjected to.
