[10000 BULK] Lock Washers External Tooth Steel Black Oxide #8

Lock Washers External Tooth Steel Black Oxide #8 deliver reliable anti-loosening performance for precision assemblies. Crafted from durable steel with a black oxide finish, these washers combine strength, a low profile, and corrosion resistance for long-lasting use in demanding environments.

The external tooth geometry bites into the mating surface to create a positive grip that resists vibration and dynamic loads. The #8 size is compatible with standard fasteners and hardware commonly used in automotive, machinery, and general assembly projects.
