The DIN 20921 washer is a type of flat washer that conforms to the DIN standard in terms of its dimensions and specifications. This standard is set by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. The DIN 20921 washer is designed to be used in various applications where a flat surface is needed to distribute the load evenly over a wider area. The dimensions of the DIN 20921 washer are precise and standardized to ensure that it can fit properly in a wide range of applications. The outer diameter of the washer typically ranges from 6mm to 42mm, while the inner diameter ranges from 1.6mm to 37mm. The thickness of the washer ranges from 0.5mm to 6mm, depending on the size and specifications required for the particular application. One of the key benefits of using DIN 20921 washers is their ability to distribute the load evenly over a larger surface area. This helps to prevent damage to the material being fastened and ensures a more secure connection. The flat shape of the washer also helps to prevent the fastener from loosening over time, providing a more reliable and durable connection

They are commonly made from materials such as stainless steel, brass, or plastic, depending on the application and environmental conditions. The washers may also be zinc-plated or treated with other coatings to prevent corrosion and improve their longevity. When selecting a DIN 20921 washer for a particular application, it is important to consider the load requirements, environmental conditions, and material compatibility. It is also essential to ensure that the washer meets the required specifications and dimensions to guarantee a proper fit and functionality. Overall, DIN 20921 washers provide a reliable and effective solution for distributing loads and securing fasteners in a wide range of applications. With their standardized dimensions, precise manufacturing, and material options, these washers offer a versatile and durable option for various industrial and construction projects. In conclusion, the DIN 20921 washer is a crucial component in many applications where a flat surface and even load distribution are essential. By adhering to the DIN standard and its precise dimensions, these washers provide a reliable and effective solution for securing fasteners and preventing damage to materials. Whether used in construction, manufacturing, or other industries, DIN 20921 washers play a vital role in ensuring the integrity and durability of connections.
