Standard:EN14399-6
Description:
The EN 14399-6 washer, also known as a structural steel washer, is a type of washer that conforms to the EN 14399-6 standard. These washers are commonly used in structural steel connections and preloaded bolt assemblies.
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.
EN 14399-6 washers can be available with two common surface finish 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 high-performance coating that provides excellent corrosion resistance. It is a thin, organic coating applied through a dip-spin process. Dacromet coatings offer superior protection against rust and corrosion, even in harsh environments or exposure to chemicals. This makes them suitable for applications where long-term corrosion resistance is required.
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. Dacromet-coated EN 14399-6 washers offer enhanced protection against corrosion and are often preferred in applications where durability and resistance to rust are critical factors.
