DIN 6798 washers are serrated lock washers designed to increase friction between fasteners and the supporting surface. Their external teeth bite into the material, helping to prevent loosening in assemblies subject to vibration or micro-movements.
They are used in electrical equipment, light mechanisms, metal fasteners and systems where friction needs to be improved without resorting to additional locking devices.
DIN 6798 washers: optimised friction to prevent loosening
At CHAVESBAO, we supply DIN 6798 washers in carbon steel and stainless steel, allowing them to be used indoors, outdoors or in assemblies with conductivity requirements. The multiple contact points provide uniform and stable locking, improving the safety of the assembly.
They are suitable for electrical panels, metal assemblies, light vibration fastenings and applications where mechanical reinforcement is required to prevent the rotation of screws or nuts.
