DIN6925 Hex Nuts All Metal Lock Nuts
DIN6925 Hex Nuts All Metal Lock Nuts
When the nut is screwed in, due to the locking function of the nut, the torque generated by screwing in the nut is called effective torque, also called locking torque. The deformed thread of the nut itself or the diameter of the built-in metal locking ring is slightly smaller than the external thread of the bolt, and the nut needs to overcome the friction resistance, which successfully prevents the nut from loosening without external force.

Main Features

  • The advantages of all-metal hexagonal locking nuts mainly include the following aspects:
  • High anti-loosening reliability: All-metal hexagonal locking nuts produce an interference fit relationship between threads through the deformation of the thread bottom hole or the deformation of the thread tooth shape, thereby increasing the friction and achieving the purpose of anti-loosening. This design performs well under vibration conditions and has high anti-loosening reliability.
  • Wide range of application: Locking nuts made of different metal materials can be used in working conditions at different temperatures and are suitable for a variety of environments and application scenarios.
  • Reusability: All-metal locking nuts can be reused, but the repeated installation should not exceed 5 times, and lubrication should be added before use.
