SUS304 Plain Galvanization DIN 6797 Serrated Lock Washers Type J Internal Teeth

DIN6797(J) SUS304 65Mn Plain Galvanization DIN 6797 Serrated Lock Washers—Type J, With Internal Teeth, Are SpecificalΦ10

DIN 6797 Serrated Lock Washers—Type J, with Internal Teeth, are specifically designed to provide additional locking and anti-loosening functionality in bolted and nutted connections. Here are the detailed descriptions of their features, advantages, and application scenarios in English:

Features

1. Internal Serrated Design: The washers feature serrated teeth on their inner surface, which bite into the threads of bolts or nuts, increasing friction and preventing loosening.
2. High Friction Coefficient: Due to the serrated design, the friction coefficient between the washer and bolt/nut is significantly increased, contributing to the stability of the connection.
3. Material Diversity: These washers are typically made of carbon steel, stainless steel, or other alloys to suit different application environments and requirements.
4. Extensive Size Range: The DIN 6797 standard specifies a wide range of sizes and specifications for the washers, catering to the needs of various bolt and nut connections.

Advantages

1. Excellent Anti-loosening Performance: With the internal serrated design, DIN 6797 washers significantly reduce the risk of connection loosening due to vibration, impact, or temperature changes.
2. Easy Installation: The installation process of these washers is simple and quick, requiring no special tools or skills.
3. Reusable: Under proper installation and disassembly, these washers can be reused multiple times.
4. Good Adaptability: Due to the material diversity and extensive size range, DIN 6797 washers can adapt to various application environments and requirements.

Application Scenarios

1. Vibration and Impact Environments: In applications such as machinery, vehicles, bridges, and other scenarios where vibration and impact are present, DIN 6797 washers effectively prevent bolt and nut loosening.
2. Temperature Change Environments: In environments with significant temperature fluctuations, connections tend to loosen due to thermal expansion and contraction. DIN 6797 washers enhance the stability of the connection.
3. High-precision Equipment: In equipment requiring precise positioning or maintaining constant connection force, such as precision instruments, aircraft, and ships, DIN 6797 washers provide reliable locking effects.
4. Heavy-duty Applications: In applications that need to bear heavy loads or high torques, such as heavy machinery and lifting equipment, DIN 6797 washers enhance the firmness and safety of the connection.
