The DIN 6923 / ISO 4162 standard specifies the characteristics of prevailing torque type hexagon nuts with flange, and with metric fine pitch thread. These nuts are designed to provide a locking feature by means of distorted threads. This standard ensures that the nuts have a consistent level of performance and reliability, making them suitable for use in a wide range of industrial and commercial applications. By providing detailed specifications for the design and dimensions of these nuts, the standard enables manufacturers to produce products that meet the necessary requirements for quality and safety. Additionally, it facilitates interchangeability and compatibility between different components and systems, ultimately contributing to the overall efficiency and consistency of mechanical assemblies.
