Spring steel lock washers with zinc plating, designed to prevent loosening under vibration and stress.
These Lock Washers are constructed from durable spring steel and finished with a corrosion-resistant zinc plating. Ideal for use in metric applications, they are engineered to resist loosening caused by vibration and dynamic loads. The split-ring design bites into the mating surface for a secure grip, making them a reliable choice in automotive, industrial, and machinery assemblies. Dimensions are provided in millimeters for precision fitting.
