The function of the spring washer:

1. The function of the spring washer is to tighten the nut, and the spring washer provides a spring force to the nut, compressing it and preventing it from falling off easily.
2. The basic function of a spring is to apply force to the nut after tightening it, increasing the friction force between the nut and the bolt.

2. Flat washers are generally not used when using spring washers (except when protecting the surface of fasteners and installation surfaces, flat washers and spring

washers are only considered)

3. Flat washers are generally used in connectors where one is soft and the other is hard and brittle. Their main function is to increase the contact area, disperse pressure,

and prevent the soft material from being crushed.

The spring washer has good anti loosening effect and seismic effect, with low manufacturing cost and convenient installation,But spring washers are greatly influenced by

material and process. If the material is not good, heat treatment is not well handled, or other processes are not in place, it is easy to crack. Therefore, it is necessary to

choose a reliable manufacturer.

So, when do we use flat washers and spring washers:

1. In general, flat washer can be used only when the load is relatively small and does not bear vibration loads.

2. When the load is relatively large and subjected to vibration loads, a combination of flat and elastic washers must be used.

3. Spring washers are generally not used separately, but rather in combination.

Overall, in practical use, due to the different emphasis on flat washers and spring washers, they are used together in many situations. This not only protects components, prevents nut loosening, but also reduces vibration, making them a great choice.
