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 imparts increased strength and durability to the washer. 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.
The term "black oxide" refers to a surface treatment applied to the washer. Black oxide is a conversion coating that provides several benefits, including improved corrosion resistance and enhanced appearance. The black oxide coating forms a thin layer on the surface of the washer, providing a protective barrier against rust and other forms of corrosion.
This type of washer is commonly used in structural steel applications, such as in construction, bridges, and other heavy-duty projects. The EN 14399-6 standard ensures that the washer meets specific requirements for dimensions, material properties, and performance.
When selecting a washer, it's important to consider the specific requirements of your application, including the load, environmental conditions, and the type of fastener being used. Consulting the relevant engineering specifications and guidelines can help ensure the appropriate washer is chosen for your specific needs.
