EN14399-6 HV300/HRC35-45 Heavy Washer, M12-M36, Zinc plated/HDG
Description:
EN 14399-6 hardened steel washers are essential components in applications where high load-bearing capacity, durability, and reliability are crucial. Their hardened steel construction, specific design features, and adherence to European standards make them ideal for use in critical structural connections that require superior strength and performance.
Heavy Washer Features :
1.Zinc plated: Zinc plating involves applying a thin layer of zinc to the surface of the washer. This coating provides moderate corrosion resistance and acts as a protective barrier against moisture and oxidation. Zinc-plated washers are commonly used in indoor or dry environments where exposure to harsh elements is limited. They offer a silver or slightly yellowish appearance.
2.Hot-dip galvanized (HDG): HDG involves immersing the washers in a bath of molten zinc, creating a thicker and more robust coating compared to zinc plating. Hot-dip galvanizing provides excellent corrosion resistance, making it suitable for use in outdoor or highly corrosive environments. HDG washers have a distinctive dull gray or matte finish.

The choice between zinc plated and HDG finishes depends on the specific application requirements, considering factors such as the operating environment and the desired level of corrosion protection. HDG is typically preferred for applications where enhanced corrosion resistance is vital, while zinc plated washers may be suitable for less demanding environments.
