The standard lock nut is a round nut with four small grooves on its outer periphery. It can be screwed on the stud body with a crescent wrench. The lock nut should be equipped with a washer for the shaft. The small groove is relatively fixed with the outer peripheral small groove to prevent it from loosening. At present, lock nuts have a variety of new designs, each of which is different, but their purpose is to prevent loosening.
Hex Bolt Manufacturers introduces the working principle of nuts is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking will be reduced in dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. One of the anti-loose measures is to use a lock nut.
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 special 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 second anti-loose method is more reliable than the first, but the structure is relatively complicated
