Heavy Hex Bolt Manufacturers describes how to prevent loosening of nuts and bolts:

  1. Loosening is one of the main failure modes of threaded fasteners. The loosening of threads has always been a serious problem in industrial manufacturing and industrial products, and even a fatal hidden danger, which has caused unpredictable harm to our daily life, work, transportation, and national defense, and military.
  2. Two requirements should be considered for the anti-loosening of the threaded coupling. One is to be reliable, and the other is to be easy to disassemble for frequent disassembly and maintenance. There are several types of anti-loosening, such as friction locking, mechanical locking, and material locking. The commonly used anti-loosing forms are mainly as follows: spring washers, elastic washers, stop washers, double nuts, lock nuts, bolts with holes Slotted nuts with split pins, adhesives, etc.
  3. (Spring, elasticity, stop) washers, rely on elastic force and the insertion of the cut corners to prevent loosening, but due to uneven elasticity, it is not very reliable. It is mostly used for insignificant connections. It is not suitable for occasions where scratches and frequent disassembly are not allowed.
  4. The locking principle of the non-metallic insert locking nut is that when the external thread is screwed in, the locking force is generated due to the good elasticity of the nylon material to achieve the locking. It can also be used to adjust the position under the condition of little vibration. However, due to the limitation of the melting point of nylon, the maximum working temperature of this kind of nuts should generally be less than 120°, preferably below 100°.
