1. Increase the contact area between the screw and the machine.
2. Eliminate the damage of the spring pad to the surface of the machine when the screw is unloaded. When using it must be: spring pad-flat pad, the flat pad is next to the surface of the machine, and the spring pad is between the flat pad and the nut. The flat pad is to increase the stress surface of the screw. In order to prevent the screw from loosening, the spring pad plays a certain amount of buffer protection when the force is applied. Although flat pads can be used as sacrificial pads.
3. But most of the time it is used as supplementary pad or flat pressing pad.
The role of Spring Washer
1. The function of the spring washer is that after the nut is tightened, the spring washer gives the nut an elastic force and presses against the nut so that it is not easy to fall off. The basic function of the spring is to give the nut a force after the nut is tightened to increase the friction between the nut and the bolt.
2. Generally, flat pads are not used when spring washers are used (except for the protection of fasteners and the surface of the mounting surface, flat washers and spring washers are considered).
3. Flat pads are generally used in connectors, one is soft and the other is hard and brittle. Its main function is to increase the contact area, disperse the pressure, and prevent the soft texture from being crushed.
