Zinc Plated External Star Washers are specialized locking washers designed with serrated teeth on the outer diameter to provide strong resistance against loosening due to vibration, impact, or dynamic loads. The sharp external teeth bite into the mating surface and the underside of the fastener head to create a firm, anti-slip grip. Coated with a zinc plating finish, these star washers offer enhanced corrosion resistance, improved durability, and a long service life in both indoor and moderate outdoor environments. Ideal for light and moderate load fastening tasks, these washers ensure secure and stable assembly performance across a wide range of industrial, mechanical, and electrical applications.
