Standard:EN14399-6
Description:
The EN14399-6 washer, also known as a flat steel washer, is a specific type of washer that conforms to the European standard EN 14399-6. This standard specifies the requirements for high-strength structural washers used in conjunction with high-strength bolts and nuts.
The EN14399-6 washer is typically made from carbon steel and is available in sizes ranging from M12 to M36. The "M" in the size specification indicates that the washer follows metric dimensions, and the number following "M" denotes the nominal diameter of the washer in millimeters.
Similar to the previous response, the washer can be found in two different finishes: plain and hot-dip galvanized (HDG). The plain finish refers to an uncoated washer with a natural steel appearance, while the HDG finish involves a coating of zinc for corrosion resistance.
It's important to note that the EN14399-6 standard specifically addresses the requirements for these washers in high-strength structural applications. The standard covers aspects such as dimensions, tolerances, materials, mechanical properties, and surface finishes.
