What are the advantages of locking nuts?

  Principle of anti loosening nut: The upper part of the conventional 60 degree tooth tip has a 30 degree wedge surface. This structure allows for increased friction between male and female threads, as well as subsequent friction between male and female threads. As the bolts are tightened with nuts, they have a function of preventing loosening. There are four methods for preventing loosening of anti loosening nuts: friction anti loosening, mechanical nut anti loosening, rivet anti loosening, and structural anti loosening.

  What are the advantages of locking nuts?

  1. Anti vibration performance: When tightening the anti loosening nut, the normal force generated is much greater than that of ordinary standard nuts, which has excellent anti loosening and anti vibration performance.

  2. Good reusability: After long-term use, the locking force does not decrease, and even if the locking nut is repeatedly tightened and disassembled, the original locking effect can still be maintained.

  3. Strong wear resistance and shear resistance: The bottom surface of the nut thread is tilted at 30 ° to evenly distribute the locking force of the nut on all threads on each tooth. Therefore, the nut can better solve the problems of screw wear and shear deformation due to the uniform compression force on the thread surface of each tooth.

  In addition, the locking nut requires a preset torque and requires a relatively large installation torque during installation. During this process, it is easy to experience the phenomenon of "biting" or "locking". If locked, it can only be resolved by cutting bolts and other damages. Before installation, pay attention to the lubrication of nuts (wax or other resin loosening agents) to reduce installation torque and speed. This can effectively reduce the locking of the locking nut.
