Hardness testing to ISO 6508-1
A Stainless Steel DIN 7349 washer is a specific type of washer that is designed to provide support, stability, and protection in various mechanical and industrial applications. The "DIN 7349" designation refers to the German Industrial Norm (Deutsche Industrie Norm) standards that govern the design and dimensions of these washers.
Stainless steel is the chosen material for these washers due to its excellent corrosion resistance, making them suitable for use in environments where exposure to moisture or harsh chemicals is a concern. Stainless steel washers are also known for their durability and longevity, ensuring a long service life.
The DIN 7349 washer is typically a flat, circular disc with a hole in the center, which allows it to be placed between a nut and a bolt or a screw and the surface it's being fastened to. Its primary purpose is to distribute the load evenly over a wider surface area, reducing the pressure on the material being fastened and preventing damage, such as indentation or deformation.
Key features of the Stainless Steel DIN 7349 washer include its uniform thickness, smooth and polished surface, and a precise inner diameter that matches the diameter of the fastener. This ensures a secure fit and even load distribution.
