Schnorr locking washer is also known as locking washer, self-locking washer, self-locking washer, din25201 locking washer, double stack self-locking washer, etc.
All kinds of machines and components can not be separated from fasteners in the connection and assembly. Fasteners bring convenience to the mechanical industry. However, it has an inevitable weakness, that is, it will loosen itself in severe vibration, causing damage, disintegration and even accidents of components or a complete equipment.

Schnorr lock washer can prevent the thread from loosening. There are many kinds of Schnorr lock washer, such as butterfly washer, saddle washer, spring washer, wave spring washer, etc.

The above types of Schnorr lock washer are based on increasing static friction to play a locking effect, low vibration, light load, uniform speed state locking effect can meet the needs of enterprises. However, in strong vibration, high load and fast motion state, it can not achieve complete anti loosening effect, but only extend the time of nut and bolt self loosening.
In order to solve this problem, scientists all over the world have done a lot of experiments and researches. In the end, they have broken through the common mistakes. 
Instead of increasing the "preload" and "friction" to achieve the anti loosening effect, they have changed the latest anti loosening principle of combining "lifting tension" and "friction" with "geometric wedge angle". This principle is not only used in the washer, but also in the nut In order to solve the problem of loose fasteners in heavy industry 
enterprises, and also solve the tedious installation, there is no need to refer to the screw in torque and screw out torque.
