    5/16″ External Tooth Lock Washer Zinc Plated

    Part #: LWE-5/16

    The 5/16″ external tooth lock washer is designed with serrated teeth around its outside diameter to securely grip the mating surface. This helps prevent loosening from vibration or torque. Zinc plating provides corrosion resistance, making it suitable for mechanical, automotive, and electrical applications where reliable fastening security is essential.
