The GB862.1 standard deals with Internal Tooth Lock Washers, which are lock washers with internal teeth used on bolts or screws to provide additional clamping force and prevent loosening. These washers are usually made from stainless steel materials such as 304 or 316 stainless steel to suit different corrosion resistance and strength requirements.
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:
Internal tooth design: The internal tooth design of DIN 6798J standard internal tooth lock washers allows them to engage tightly with the threads of bolts or screws, providing strong anti-loosening performance. High Strength Material: Usually made of high strength stainless steel materials such as A2-70 or A4-70, these materials have good mechanical properties and corrosion resistance. Surface treatment: The surface of the washer may be zinc plated or other surface treatments to improve corrosion and wear resistance.
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.
