The lock nut can be screwed on the stud body with a crescent wrench. The lock nut should be equipped with a washer for the shaft, which can make the small groove on the stud body relatively fixed with the small groove on the outer circumference to prevent it from loosening. The lock nut has a variety of new designs, each of which is different, but its purpose is to prevent loosening. So everyone knows how to lock the lock nut?
The working principle of the lock nut is self-locking by the friction between the nut and the bolt. The reliability of this self-locking is reduced in 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 be screwed on the same bolt, and a tightening torque is added between the two nuts to make the bolt connection reliable. The other is a lock nut, which needs to be used with a lock washer. The special lock nut is not a hexagonal nut, but a middle round nut. There are 6 notches on the circumference of the nut. These six notches are not only the focus point of the tightening tool, but also the locking point of the lock washer. . The two anti-loose methods are more reliable than one, but the structure is relatively complicated.
When we all lock the lock nut, we all need to operate according to the locking method of the lock nut. The correct locking of this nut is what we all need.
