DIN 9021 Washer/Zinc Plated Washer, M6-M100

DIN 9021 washers, also known as plain washers or flat washers, are a type of washer that conforms to the DIN 9021 standard. These washers have a flat, circular shape with a centrally located hole. They are used to provide a smooth bearing surface and distribute the load of a threaded fastener, such as a bolt or a nut.

The size range you mentioned, M6 to M100, indicates the metric thread size compatibility of the DIN 9021 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 9021 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 9021 Washer/Zinc Plated Washer, M6-M100," it means that DIN 9021 washers are available with a zinc plated finish in the M6 to M100 size range. This combination provides the benefits of both the flat washer design specified by DIN 9021 and the corrosion resistance of the zinc plating.

Zinc plated washers are commonly used in a wide range of applications, but it's important to consider the specific environmental conditions and requirements of your project. In highly corrosive or harsh environments, alternative coatings or materials with higher corrosion resistance may be necessary.
