DIN6798A External Tooth Lock Washers Zinc Plated

External Serrated Lock Washers 

Zinc electroplated serrated lock washers are a type of washer that has serrations on one side to help prevent loosening of the fastener. These washers are made of steel and have a zinc coating applied through the process of electroplating, which provides corrosion resistance and a decorative finish. The serrations on the washer create a locking effect when the washer is tightened against the surface, helping to keep the fastener in place and prevent it from loosening over time. These washers are commonly used in applications where vibration or movement may cause traditional washers to come loose, such as in automotive, construction, and industrial settings.
