Prevent loose - double nut fastening method

In daily life, when we are loading screws and nuts, the nut loose phenomenon is often a thing, and we sometimes see a lot of bolts will be used with two nuts, so whether it can prevent the bolt loose? Yes, the following China Standard parts network will provide the prevention of loose - double nut fastening method.

In the case of double nut fasteners, the friction between the threads or the support surfaces of the bolts and nuts can be increased, or the friction between them can be increased to make the nuts loose-proof. Through this method, the biggest benefit of anti-loose can not affect its use because of the factors of space, but also can be disassembled for many times, to achieve the purpose of mobile assembly. So this is the most popular method.

In addition, nuts and bolts of the same height can also be used to tighten, so that the friction of the thread is more effective to avoid loosening. In the process of assembly, the inner nut can be tightened by 80% of the assembly torque, and then the outer nut can be tightened by 100% of the torque. In this way, the nut and bolt will be tighter, and the friction resistance will be significantly improved. This is a relatively simple structure of the assembly mode, effectively avoid the problem of loosening. But the nut also weighs more and requires more room to install, which is also a disadvantage.

The use of fasteners and the prevention of loose problems are common problems, but we must also take corresponding measures, if we do not notice that fasteners have loose phenomenon, it is likely to lead to some accidents.
