Standard:DIN6916
Description:
DIN 6916 washers, also known as heavy hex structural washers, are a specific type of washer that conforms to the DIN 6916 standard. These washers are designed for use in high-strength structural bolting assemblies and are commonly used in heavy-duty construction and industrial applications.
The size range you mentioned, M12 to M36, indicates the metric thread size compatibility of the DIN 6916 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 DIN 6916 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 "DIN 6916 Washer/Zinc Plated Washer, M12-M36," it means that DIN 6916 washers are available with a zinc plated finish in the M12 to M36 size range. This combination provides the benefits of both the heavy hex structural washer design specified by DIN 6916 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 DIN 6916 standard for proper usage and compatibility with structural bolting assemblies.
