DIN 6921 Hexagon Flange Toothed Bolts Galvanized

Why use DIN 6921 flat disc bolts?

Main advantages of using DIN 6921 flat disc bolts:

1. Integrated washer design: The head of DIN 6921 flat disc bolts is designed with an integrated washer, which not only improves the tightening force between the bolt and the contact surface, but also reduces the need for additional washers and simplifies the assembly process.

2. Anti-loosening performance: The flat disc design of the bolt head can increase the friction with the contact surface, thereby effectively preventing the bolt from loosening. This is especially important for equipment and mechanical applications with frequent vibrations, such as automobiles, construction machinery, etc.

3. Uniform force: The flat disc head provides a larger contact surface, which can evenly distribute the tightening force of the bolt, reduce the pressure concentration on the fixed material, and reduce the risk of material deformation.

4. Easy installation: The integrated washer design makes the installation process easier, without the need to add additional washers, reducing assembly time and improving efficiency.

5. Corrosion resistance: These bolts are usually made of high-strength materials, such as stainless steel or galvanized carbon steel, which have good corrosion resistance and are suitable for use in harsh environments.

6. Wide application: DIN 6921 flat plate bolts are widely used in many industries, such as automobile manufacturing, heavy machinery, and construction industries, such as fixing elevator guide rail brackets or guide rails themselves to walls, and installing buffers and buffer bases in elevator shafts. They are especially suitable for applications that require fasteners to have high strength and reliable anti-loosening performance.
