Spring washer can play a loose-proof, increase the pretension function, while the flat washer does not have this function, it can be used to increase the fastening contact area, prevent the friction between bolts and the workpiece, protect the surface of the connector from cutting the workpiece surface when the bolts and nuts are tightened.
But some important connections, such as mainly rely on compression friction to transfer the power of the place, is not the use of spring pad, with the reduced rigidity of the connection, it is easy to have an accident. You can do without a spring washer. When the strength of the connector is low, use flat pad or flange bolts to increase the contact area. When there are large fluctuations in the temperature of vibration, pulse and medium, spring pad must be used.
