DIN 20921 Washer Dimensions DIN 20921 washers are crucial components in various mechanical and industrial applications. These washers are designed to distribute the load of a threaded fastener, such as a bolt or nut, over a larger surface area to prevent damage to the material being fastened. Understanding the dimensions of DIN 20921 washers is essential to ensuring proper installation and functionality. The dimensions of DIN 20921 washers are standardized to ensure compatibility with fasteners and components from different manufacturers. These washers are available in various sizes to accommodate different thread sizes and applications. The dimensions of DIN 20921 washers include the outer diameter, inner diameter, and thickness of the washer. The outer diameter of DIN 20921 washers is the measurement across the widest part of the washer. This dimension is important for determining the size of the washer and ensuring a proper fit with the fastener and the material being fastened. The inner diameter of DIN 20921 washers is the measurement across the center hole of the washer. This dimension is important for ensuring that the washer fits securely around the fastener without interfering with the threading. The thickness of DIN 20921 washers is the measurement of the distance between the outer and inner surfaces of the washer
