External tooth lock washers according to DIN 6797 A are lock washers with external teeth, which are mainly used to provide locking of bolted or screwed connections. These washers have outwardly extending teeth on their outer edges, which bite into the surface of the connected parts when installed to prevent loosening due to vibration or shock.
Carbon Steel: Typically used for general applications.
Stainless Steel: For environments where corrosion resistance is required.
Alloy Steels: Used in applications requiring high strength or high temperature resistance.
Advantage:
EFFICIENT LOOSENING PREVENTION: The teeth of the outer tooth lock washers are located on the largest radius, providing greater torsional resistance for efficient loosening prevention. MATERIAL STRENGTH: Typically made of spring steel with a hardness between 350-425 HV10, ensuring the strength and durability of the washers. Surface Finish: Can be electro-galvanized, natural color or other surface finishes to improve corrosion resistance and adapt to different working environments. Multiple Sizes: A wide range of sizes are available to accommodate bolts and screws of different diameters, ranging from M1.6 to M30.
Scope of Application
Mechanical Manufacturing: In the field of mechanical manufacturing, it is used to fix rotating or sliding parts such as gears, bearings and bushings. Automotive industry: in the engine, gearbox, chassis and other key parts of automobiles to ensure the correct positioning and fixation of parts. Electrical equipment: In electrical equipment, used to keep electrical connectors and terminals in place and prevent loosening due to vibration. Aerospace: In aerospace, to ensure the precise installation and fixing of critical components to withstand extreme operating conditions.
