Common methods of locking screws

How many important methods are there to prevent loosening screws? There are several ways to prevent screws from loosening, which mainly refers to the friction. The effect of preventing screws from loosening depends on the third force. It does not depend on a third force but on its own structure. Structurally resistant to loose styles of Tang thread locks, Tang lock patterns are currently the most advanced, best, but not applicable to most people know.

The main anti-loosening methods of screws are as follows:

First: the structure is loose. It is the use of the spiral structure itself. Tang thread locks pattern.

Second: Riveting stamping anti-loose, in the use of point welding, bonding and other methods. So, that the screw connection becomes a non - detachable connection. The disadvantage of this method is that the bolt rod can only be used once removing it is very difficult and must be detachable on the side of the fault bolt.

Third: Mechanical anti-loosening. Rotation relative to a pair of threads restricted by a stopper when the nut is loosened back to the stop position, the anti-loosening stop can work, so this way is not actually anti-loosening but prevent falling.

Fourth: Friction anti loose. This is the most widely used anti-loosening method, in which a screw produces a friction screw that does not change with the external pressure of the screw, in order to produce a screw that can prevent a pair of relative rotations. It achieves positive pressure at the same time by axial or two pressing screws. Such as the use of elastic washers, double nuts, self-locking nuts, nylon locking nuts, etc.
