Flat pad and spring pad,What will Nigerian engineering companies do？

When do you use flat pads and when do you use spring pads

1. Under normal circumstances, flat pads can be used only when the load is relatively small and the vibration load is not borne.
   In the case of large load and vibration load, a combination of flat pad and spring pad must be used.
   3. Spring washers are basically not used alone, they are used in combination.

The function of the spring pad

1. The function of the spring washer is that after tightening the nut, the spring washer gives the nut a elasticity to tighten the nut so that it is not easy to fall off. The basic function of the spring is to give a force to the nut after the nut is tightened to increase the friction between the nut and the bolt.
2. Flat pads are generally not used with spring pads (in addition to protecting the surface of fasteners and mounting surfaces, flat pads and spring pads are considered).

3, flat washers are generally used in connection parts, one is soft texture, one is hard and brittle, its main function is to increase the contact area, disperse the pressure, to prevent the soft texture of the crush.

The role of the flat pad

1. Increase the contact area between screw and machine
2. Eliminate the damage to the surface of the machine when the spring pad is unloading the screws. When used, it must be: spring pad a flat pad, the flat pad is next to the machine surface, and the spring pad is between the flat pad and the nut. The flat pad is to increase the force surface of the screw. In order to prevent the screw from loosening, the spring pad plays a certain buffer protection role when it is stressed. Although flat pads can be sacrifice pads.

3, but more often it is used as a supplementary pad or flat pad.

Generally, Nigerian companies will conduct technical bidding before the implementation of the project, and the design scheme will be selected according to the project requirements.Most of the bolts purchased from us by Daewoo Group in South Korea are flat washers, which will eventually be used to fix the train 7 platform in Nigeria.
