How to lock the square nut?

The lock nut can be tightened on the stud body with a crescent wrench, and the lock nut should be equipped with a shaft washer, which can make the small groove on the stud body relatively fixed with the small groove on its outer circumference to prevent it from loosening. There are various new designs of lock nuts, all of which are designed to prevent loosening. So do you know how the lock nut needs to be locked?
The working principle of the lock nut is to use the friction between the nut and the bolt for self-locking. The reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking.
There are also two types of lock nuts. One is to use two identical nuts to screw on the same bolt, and add a tightening torque between the two nuts to make the bolt connection reliable. The other is a locking nut, which needs to be used together with a locking washer. The special anti-loosening nut is not a hexagonal nut, but a medium-round nut. There are 6 gaps on the circumference of the nut. These six gaps are not only the focal point of the tightening tool, but also the insertion place of the anti-loosening washer bayonet. . Two anti-loosening methods are more reliable than one, but the structure is relatively complex.
When we all lock the lock nut, we all need to operate according to the locking method of the lock nut. Correctly locking this nut is what we all need.
