1. DIN 6916 is a standard that specifies the dimensions and requirements for structural washers made of steel. These washers are designed to distribute the load of a bolt or screw over a larger area, helping to prevent damage to the material being fastened. The standard covers washers with a large outer diameter and a small inner diameter, ensuring a secure fit with the fastener.

2. DIN 6916 washers are commonly used in construction and engineering applications where heavy loads or vibrations are present. By providing a larger surface area for the bolt or screw to press against, these washers help to increase the stability and strength of the connection. This can be especially important in critical applications where failure could have serious consequences.

3. When using DIN 6916 washers, it is important to ensure that they are installed correctly and in accordance with the standard guidelines. This includes making sure that the washer is positioned correctly under the head of the fastener and that it is tightened to the appropriate torque specifications. By following these guidelines, the washer can effectively distribute the load and help to prevent loosening or failure of the connection.
