If the surface of the fastened part or component is rough, under strong vibration, the surface will wear and become smooth, resulting in a gap and a decrease in axial force. For this type of application, re-twisting is required. The number of re-twisting should be determined based on experiments.

Yes. ESLO lock nuts have been used in the steel structure connection of Shanghai maglev high-speed trains, and the effect is good. Its torque coefficient is slightly higher than that of standard threads.

Generally speaking,only be used for rigid connection. If you have special requirements, please contact our engineers

It can be seen from the vector analysis diagram in Figure 2 that under the same torque, the clamping force produced by the variable tooth type anti-loosening thread is smaller than the clamping force produced by the standard thread. To achieve the same clamping force, the torque must be increased. U......

The ESLO lock nut and bolt are loosened after tightening, and the tip of the bolt is slightly deformed. This is due to the special 30 degree wedge thread.
It should be no problem to screw the bolts on deformed tooth tips with ordinary nuts. However, we do not recommend such applications.

-Any hard joint
-Thin gasket application
-High vibration working environment 
-High temperature joint or working environment
