Product Picture
DIN 7965 grounding washer is also known as grounding conical anti-loosening lock washer. It is an improved disc-shaped product with teeth on the top and six claws on the bottom, featuring an inherent taper. Widely used in electrical appliances, elevators, and mechanical equipment, its working principle relies on the tension generated by the rebound force after compression, which drives the dual-sided serrations to prevent loosening and slipping.
It is used for connecting wires in electrical equipment and grounding connections in electrical cabinet manufacturing. Made from tempered spring steel, its high hardness ensures that all six claws embed into the base material after installation, providing excellent contact. When bolts are tightened, it guarantees optimal grounding performance. The serrated design increases friction, delivering superior anti-loosening effects.
