Description:

EN 14399-6 washers, also known as heavy washers, are designed to be used in high-strength structural bolting assemblies. These washers conform to the EN 14399-6 standard, which specifies their dimensions, material requirements, and mechanical properties. The parameter you mentioned, M12-M36, indicates that these washers are available in metric sizes ranging from M12 to M36.

When specified with a "Black Oxide" finish, EN 14399-6 washers have undergone a surface treatment process known as black oxide coating. Black oxide coating, also referred to as blackening, is a conversion coating that creates a thin layer of black oxide on the surface of the washer.

The black oxide coating serves multiple purposes. First, it provides a degree of corrosion resistance, although its level of protection may not be as high as that of other coatings like hot-dip galvanizing or Dacromet. Second, the black oxide finish enhances the aesthetics of the washers, giving them a sleek black appearance. Lastly, the black oxide layer can improve the wear resistance and lubricity of the washers, facilitating smooth assembly and operation.

EN 14399-6 washers with a black oxide finish are commonly used in applications where both structural strength and visual appeal are important. They are suitable for use in various industries, including construction, engineering, and machinery.
