DIN6923 Hex Flange Nut

1. Increase the contact surface and force area: One end of the hexagonal flange nut has a wide flange (i.e. flange surface), which increases the contact area between the nut and the workpiece. According to the principles of mechanics, the larger the force area, the smaller the pressure on the force surface, thereby improving the load-bearing capacity and stability of the nut. 2. Sealing: Due to the hexagonal flange nut having a flange surface fixed on one end of the nut body and a cap fixed on the other end, this design has good sealing performance during use, which can effectively prevent harmful substances such as rainwater, moisture, dust, etc. from entering the nut body, prevent the nut body from rusting, and thus extend its service life. 3. Wide application: Hexagonal flange nuts are widely used in various industrial and civilian fields. For example, they are commonly used in applications such as pipeline connections, stamped parts, and castings that require increased contact surface stability. In addition, hexagonal flange nuts are also used in heavy machinery, automotive engines, and other applications that require high preload force and good anti loosening performance.
