Product Description


      The EN 14399-6 washer, also known as a hardened steel washer, is a type of washer that conforms to the EN 14399-6 standard. It is commonly used in structural steel applications where high-strength fasteners are employed.

      The EN 14399-6 washer is made from hardened steel, which provides increased strength and durability. It is available in various sizes ranging from M12 to M36, with the "M" indicating the metric thread size and the number representing the nominal diameter of the fastener it is designed to be used with.

      In terms of surface finishes, EN 14399-6 washers can be found in two main variants: plain and Dacromet.

      1.Plain Finish: Plain finish washers have a basic, uncoated surface. They are typically used in applications where corrosion resistance is not a primary concern, such as in dry environments or when the fasteners are protected by other means (e.g., coatings, lubricants).

      2.Dacromet Coating: Dacromet is a type of coating that provides excellent corrosion resistance to the washer. It is a thin, non-electrolytic coating that offers superior protection against rust and other forms of corrosion. Dacromet-coated washers are commonly used in applications where exposure to moisture, chemicals, or other corrosive elements is expected.

      The choice between a plain finish and Dacromet coating depends on the specific requirements of your application, including the environmental conditions and the level of corrosion resistance needed.

      It's important to note that the EN 14399-6 standard ensures that the washer meets specific requirements for dimensions, material properties, and performance. This standard is commonly used in Europe for structural steel applications.

      When selecting a washer, it's crucial to consider the specific requirements of your application and consult the relevant engineering specifications and guidelines to ensure the appropriate washer is chosen for your needs.
