Spring washers are used to prevent loosening, flat washers have no relaxation function, that is, flat washers only increase the contact area, and spring washers can prevent loosening.
Flat pads: just increase the surface area to prevent damage to the mounted parts of the soft substrate or to block the holes.
The difference between a spring washer and a flat washer is edited by voice
Spring washer can play a loose, increase the function of pretightening force, and flat washer does not have this function, it can be used to increase the fastening contact area, prevent the friction between the bolt and the workpiece, protect the surface of the connector to prevent scratching the workpiece surface when the bolt and nut tighten.
But some important connections, such as mainly rely on compression friction to transfer power, is not the use of spring pads, with the reduction of connection rigidity, the accident is easy. You don’t need a spring washer. When the strength of the connecting piece is low, the flat pad or flange bolt is used to increase the contact area. When there is vibration, pulse, and the temperature of the medium, the spring pad must be used.
Spring pad: After locking, use the elasticity of the spring pad to prevent loosening

Frequently Asked Questions
What is the difference between a spring washer and a flat washer?
A spring washer is designed to prevent loosening by utilizing its spring elasticity to maintain tension after locking. In contrast, a flat washer does not have a relaxation function; it is used to increase the contact surface area, distribute the load, and protect the surface of the connector from scratches during tightening.
When is it necessary to use a spring washer?
Spring washers must be used in environments subject to vibration, pulse, or medium temperature variations to prevent the fasteners from loosening under dynamic loads.
