How do spring washers work?

In theory split washers (aka lock washers or helical spring washers) are supposed to work by squishing flat between the nut and the mounting surface when you tighten them. At this point the sharp edges of the washer are supposed to dig into the nut and mounting surface to prevent counter-clockwise rotation.

Regarding this, what does a spring washer do?

Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations. Locking washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.

Subsequently, question is, where should spring washers be used? Place the lock washer under the threaded fastener. To help it accomplish this, put the lock washer on first, below the fastener. If your project calls for other washers or hardware elements, they should go on before the lock washer so that it can hold them in place.

One may also ask, how do you use a flat washer and a spring washer?

Ideally the lock washer goes into the threaded fastener first followed by the flat washer. This way the lock washer adds tension to the fastener assembly. It creates pressure on the bolt or nut (depending on where it is used) to prevent the assembly from loosening when it is exposed to vibration.

How do you fit a spring washer?

The order should be bolt head, flat washer, materials being clamped, flat washer, spring washer, nut. If you only have one flat washer per bolt, and if the material next to the bolt head is sufficiently hard to resist deformation, then the one flat washer should be on the nut side.
