[10000 BULK] Lock Washers External Tooth Steel Zinc #3

Discover reliable anti-loosening performance with the Lock Washers External Tooth Steel Zinc #3. Engineered for high-vibration environments, these washers keep fasteners firmly in place, even under dynamic loads.

Featuring external tooth design, the teeth bite into the mating surface, creating a secure grip that resists loosening where ordinary washers fail. The result is enhanced joint integrity across a wide range of mechanical, automotive, and electrical assemblies.

Built from high-grade steel and finished with zinc plating, these lock washers deliver durable corrosion resistance and long-lasting performance in harsh conditions. The #3 size is compact yet effective, making it ideal for smaller fastener applications without sacrificing locking power.
