Description:

The DIN 9021 washer, also known as a flat steel washer, is a widely used washer in various industries and applications. It is designed to distribute the load of a threaded fastener, such as a bolt or a nut, and provide a smooth bearing surface. The DIN 9021 washer conforms to the specifications outlined in the German Industrial Norm (DIN) 9021.

One particular variation of the DIN 9021 washer is the version with a black oxide finish. The black oxide finish is a type of surface treatment that provides a dark, protective layer on the washer. This finish not only enhances the aesthetics of the washer but also offers some corrosion resistance.

The process of achieving a black oxide finish involves a chemical conversion of the washer's surface into magnetite (Fe3O4), which provides a durable and attractive black coating. The black oxide finish can help protect the washer from rusting and other forms of corrosion, making it suitable for applications in environments where moisture or exposure to harsh conditions is a concern.

The DIN 9021 washer with a black oxide finish is available in a size range from M6 to M100. This indicates that it is available in various diameters to accommodate different sizes of bolts or nuts.
