Our Zinc Plated External Tooth Lock Washers are a dependable fastening solution for applications that require added resistance to loosening. Designed with external serrations, these washers bite into the surface material as well as the underside of the bolt head, screw head, or nut, creating a locking effect that helps maintain a secure connection.
Finished with a zinc plated coating, these washers offer added protection against corrosion while remaining suitable for a wide range of general engineering, industrial, automotive, and maintenance applications. They are commonly used where vibration could cause standard fasteners to work loose over time.
