The anti loosening principle of the waveform washer is that after pressing the waveform washer flat, the waveform washer will generate a continuous elastic force, which will maintain a frictional force between the nut and bolt thread connection pair, generate a resistance torque, and prevent the nut from loosening. At the same time, the sharp corners at the opening of the waveform washer are embedded into the bolt and the surface of the connected part respectively, thereby preventing the bolt from rotating relative to the connected part.

What is the anti loosening effect of the waveform washer?

Waveform washers are widely used in load-bearing and non load-bearing structures of general mechanical products, characterized by low cost, convenient installation, and suitable for frequently installed and disassembled parts. But the anti loosening ability of the waveform washer is very low! Especially in the current European and American countries, the adoption rate of high reliability products is extremely low, especially the important load-bearing structural join parts have been abandoned for many years. Our country still has some applications in military industry, but it has been improved to stainless steel material. It is said that the use of steel corrugated washers has long been prohibited in CASC! It can also be said that it is very unsafe for two reasons: firstly, it is due to rising circles, and secondly, it is due to hydrogen embrittlement.
