External Tooth Lockwasher, Zinc Cr+3 (Inch)
External Tooth Lock Washers with a Zinc Cr+3 finish are designed to improve fastener security by using sharp, outward-facing teeth that bite into the mating surface. This aggressive locking action helps prevent loosening caused by vibration, motion, or thermal expansion. The Zinc Cr+3 plating offers enhanced corrosion resistance and a clean, bright appearance suitable for both indoor and light outdoor environments.
These washers are ideal for applications requiring strong locking performance on large bearing surfaces or softer materials, such as electrical assemblies, appliances, machinery, and general-purpose industrial equipment. The outward tooth configuration provides maximum frictional grip, while the corrosion-resistant zinc finish ensures reliable long-term performance and durability.
