DIN6797(A) 65Mn Zinc Plating Toothed Lock Washers—Type A,With External Teeth Φ6-Φ10
DIN 6797(A) defines the standard for Type A toothed lock washers with external teeth. The key features, advantages, and applications of this type of washer are as follows:
Features
- External Teeth Design: The washer features a series of raised teeth around its perimeter, which can embed into the softer material of the substrate or adjacent components during installation, providing an additional locking effect.
- High Strength: These washers are typically made from high-strength materials, such as stainless steel or carbon steel, ensuring they maintain their locking function under vibration or impact.
- Anti-loosening Performance: The external teeth of the DIN 6797(A) washer effectively prevent bolts or nuts from loosening under vibration or dynamic loads.
Advantages
- Enhanced Safety: In applications requiring high reliability, such as heavy machinery, bridges, and buildings, this washer significantly reduces safety hazards caused by loose bolts or nuts.
- Reduced Maintenance Costs: As it reduces the need for frequent inspections and re-tightening due to loosening, it can lower the maintenance costs of equipment.
- Strong Adaptability: This washer is compatible with various types of bolts and nuts, and it can be used with multiple materials, such as steel, aluminum, and plastic.
Applications
- Heavy Machinery and Equipment: In environments that require withstanding high vibration and impact loads, such as excavators, cranes, and compressors, the DIN 6797(A) washer provides reliable locking.
- Bridges and Building Structures: In bridges, buildings, and other structures that need to endure natural forces like wind and earthquakes, this washer ensures the tightness of bolts or nuts, enhancing the structural safety.
- Vehicles: In automobiles, trains, aircraft, and other modes of transportation, the DIN 6797(A) washer is widely used for securing critical components to prevent loosening during operation.
