Internal/External Tooth Lock Washers, Zinc Cr+3 (Inch)
Internal/External Tooth Lock Washers with a Zinc Cr+3 finish provide enhanced fastening security by combining both inward- and outward-facing teeth for maximum gripping strength. This dual-action design increases friction on both the fastener and the mating surface, helping prevent loosening caused by vibration, shock, or movement. The Zinc Cr+3 coating offers clean appearance and reliable corrosion resistance for indoor and light outdoor environments.
These washers are ideal for electrical assemblies, appliances, light machinery, and applications requiring secure fastening on a variety of surfaces. The internal teeth grip the fastener head for stability, while the external teeth anchor into the material for additional holding power. This versatile washer design delivers balanced, dependable locking performance and long-term durability with added protection from rust.
