Product Description

DIN6798(A) 65Mn/SUS304 Galvanization/Plain Serrated Lock Washers—Type A,With External Teeth Φ3-Φ20

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

  1. 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.
  2. 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.
  3. 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

  1. 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.
  2. 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.
  3. 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

  1. 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.
  2. 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.
  3. 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.
