DIN 7089 compliant with the standard flat washers, By distributing surface pressure over a wide area in bolt and nut connections, it prevents the fasteners from damaging the surface. These washers, which are particularly preferred in large-diameter or high-tension connections, help prevent the connection from loosening. They have a wide range of applications, from industrial equipment to steel structures.

DIN 7089 flat washers distribute pressure across the surfaces where bolts and nuts are fastened, preventing surface damage and loosening. They also ensure that fasteners have a longer service life.
It is frequently preferred in industrial machinery, steel construction assemblies, energy facilities, and infrastructure projects. It is also used to increase stability in vibrating environments.
It is usually made of carbon steel, but material options such as stainless steel (A2/A4), aluminum, and brass can also be offered depending on the application requirements.
