Standard:EN14399-6
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: zinc plated and HDG (Hot-Dip Galvanized).
1.Zinc Plated: Zinc plating is a common surface finish for washers. It involves applying a thin layer of zinc coating to the surface of the washer. Zinc plating provides moderate corrosion resistance and can help protect the washer from rust and other forms of corrosion. It is often used in applications where the washer is not exposed to harsh environments or where additional corrosion protection measures are applied.
2.HDG (Hot-Dip Galvanized): HDG is a more robust and durable surface finish for washers. It involves immersing the washer in a bath of molten zinc, which forms a thick, protective coating on the surface. HDG provides excellent corrosion resistance, making it suitable for applications where the washer will be exposed to harsh or corrosive environments. It is commonly used in outdoor applications, such as construction, infrastructure, and marine projects.
The choice between zinc plated and HDG 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.
