Standard:EN14399-6
Description:
EN 14399-6 washers, also known as high tensile washers or structural washers, are designed for use with high-strength structural steel bolts according to the EN 14399 series of standards. These washers conform to the requirements specified in the EN 14399-6 standard, which defines the dimensions and material properties for these washers.
The size range of EN 14399-6 washers is typically specified in metric measurements, such as M12 to M36. This indicates that EN 14399-6 washers can accommodate metric fasteners with diameters ranging from M12 to M36.
EN 14399-6 washers are available with two common coating options: plain and Dacromet.
Plain EN 14399-6 washers do not have any surface coating or treatment. They are made from bare steel and provide basic protection against corrosion. Plain washers are typically used in applications where corrosion resistance is not a significant concern or where additional coating or protection measures will be applied.
Dacromet is a specialized coating option for EN 14399-6 washers. Dacromet is a non-electrolytic, water-based coating that provides excellent corrosion resistance. It forms a thin, uniform coating that offers a high level of protection against rust and other forms of corrosion. Dacromet coatings are designed to withstand harsh environmental conditions, including exposure to moisture, salt spray, and chemicals. Additionally, Dacromet coatings provide good adhesion and act as a self-lubricant, reducing friction during assembly.
When choosing between plain and Dacromet EN 14399-6 washers, consider the specific environmental conditions in which they will be used. If the application involves exposure to moisture, humidity, or corrosive substances, Dacromet-coated EN 14399-6 washers would provide superior corrosion protection. For applications where corrosion resistance is not a significant concern or where additional protective measures will be applied, plain EN 14399-6 washers may be suitable.
