- DIN 7989 outlines the requirements for circular washers with a flat shape and a chamfer on one side. These washers are commonly employed to distribute the load of threaded fasteners, such as bolts or nuts, across a larger surface area. By doing so, they help prevent damage or deformation of the connected materials.
- In accordance with DIN 7989, these washers are typically manufactured using steel and are available in various sizes, ranging from M1.6 to M64, which correspond to different thread diameters.
- The standard provides detailed information regarding the dimensions of the washers, including outer and inner diameter, thickness, and chamfer dimensions for each size.
