External Tooth Lock Washer (DIN 6797A / GB 861.2)
External tooth lock washers feature teeth pointing outward, maximizing surface contact and providing superior locking performance on large bearing surfaces. They are widely used to prevent rotation and loosening in dynamic or high-vibration environments.



Features and Performance:
• Material Options:
• Carbon Steel (65Mn, C75S): Offers durability and resilience for demanding applications.
• Stainless Steel (AISI 304, 316): Delivers excellent resistance to rust and corrosion in challenging conditions.
• Specialty Metals (Brass, Phosphor Bronze): For electrical or aesthetic purposes.
• Surface Treatment:
• Zinc plating, black oxide, or nickel plating for corrosion resistance.
• Custom coatings available to meet specific environmental or operational needs.
• Performance:
• Outward-facing teeth bite into the mating surface, ensuring strong resistance to loosening.
• Distributes load effectively and prevents joint slippage.
Applications:
• Frequently used in automotive, industrial, and aerospace sectors to secure bolts and screws in high-vibration settings.
• Particularly effective in assemblies where a larger contact area is required for enhanced stability.
Advantages of Both Washers:
• Strong locking performance under dynamic loads.
• Easy to install and compatible with a wide range of fasteners.
• Available in various sizes, materials, and finishes to suit diverse applications.
