Lock Washers External Tooth Steel Zinc 7/16 are durable, serrated washers designed to prevent loosening in vibrating assemblies. Made from hardened steel with a zinc finish for corrosion resistance, these external-tooth lock washers bite into both the bolt and mating surface to create a secure, vibration-resistant fastening.

Key Features

• Material: steel with zinc plating provides corrosion resistance and strength.
• Design: external tooth (serrated) edges bite into surfaces for a secure grip.
• Size: 7/16-inch diameter to fit corresponding bolts and fasteners.
• Performance: helps prevent loosening from vibration and dynamic loads.
• Finish: zinc coating offers additional protection against rust.

Applications

Ideal for automotive, machinery, equipment, and general mechanical assemblies where a reliable locking action is required. Suitable for standard bolt sizes that match the 7/16-inch specification.

Installation Tips

• Place the washer between the bolt head and the surface. Ensure the serrations engage the load-bearing surface for best grip.
• Tighten to the recommended torque for your fastener size and material to maximize locking performance.
• Use with compatible bolts and ensure surfaces are clean and free of debris for optimal bite.

Choose these external-tooth lock washers in zinc-plated steel for dependable locking power on 7/16" fasteners, engineered to resist vibration and corrosion.
