Main purpose of spring washers
The spring washer device is under the nut to prevent the nut from loosening.

The hexagon slotted nut is specially used with the bolt with hole at the end of the screw to insert the cotter pin into the hole of the screw from the slot of the nut to prevent the nut from loosening automatically. It is mainly used for occasions with vibration load or alternating load.
The methods to prevent automatic loosening of nuts (or bolts) in mechanical design and manufacturing are as follows:
1. Add spring washer; (Easy to do)
2. Use hexagon slotted nut+cotter pin; (Processing procedures were added on a year-on-year basis)
3. Add washer; (Processing procedures were added on a year-on-year basis)
4. The hexagon head opening of the hexagon bolt is inserted into the steel wire. (Processing procedures were added on a year-on-year basis)
