EN14399-6 Washer/Zinc Plated Washer, M12-M36
Standard:EN14399-6
Description:
EN 14399-6 washers, also known as high-strength structural washers, are a specific type of washer that conforms to the EN 14399-6 standard. These washers are designed for use in high-strength structural bolting assemblies. They are commonly used in heavy-duty construction and industrial applications where strong and reliable connections are required.
The size range you mentioned, M12 to M36, indicates the metric thread size compatibility of the EN 14399-6 washers. These washers are designed to be used with bolts or studs that have metric thread sizes within this range.
The "zinc plated" specification indicates that the EN 14399-6 washers are coated with a layer of zinc to provide corrosion resistance. Zinc plating is a common surface treatment for washers and other fasteners. It creates a protective barrier that helps prevent the underlying steel from coming into direct contact with moisture or corrosive substances, reducing the risk of rust and corrosion.
When specified as "EN 14399-6 Washer/Zinc Plated Washer, M12-M36," it means that EN 14399-6 washers are available with a zinc plated finish in the M12 to M36 size range. This combination provides the benefits of both the high-strength design specified by EN 14399-6 and the corrosion resistance of the zinc plating.
It's important to note that while zinc plating offers good corrosion resistance, it may not be suitable for highly corrosive or harsh environments. In such cases, alternative coatings or materials with higher corrosion resistance may be required. Additionally, it's important to follow the specific requirements and guidelines of the EN 14399-6 standard for proper usage and compatibility with structural bolting assemblies.
