Specifications

• Material: 18/8 stainless steel
• Finish: Black oxide
• Type: External lock washer
• Size: #3/8

Benefits

External lock washers bite into the mating surface and the fastener head to resist loosening caused by vibration and dynamic loads. The 18/8 stainless construction offers excellent corrosion resistance, making them suitable for challenging environments.

Applications

Ideal for automotive, machinery, and general hardware assemblies where secure fastener performance is required.

How to Use

Place the external lock washer between the fastener head (or nut) and the mating surface. As the fastener is tightened, the washer’s teeth engage the surface, creating a locking action that helps prevent loosening under vibration.

Care & Maintenance

Store in a dry environment to preserve finish. If used in corrosive or marine environments, inspect for wear and reapply or replace as needed to maintain locking performance.
