Spring lock washers provide a positive locking action. Spring like take-up compensates for loosening caused by slight material wear. Lock washers can help with this situation by applying a spring force against the nut or bolt head. Any stretching or flattening of parts is likely to be much less than the compression of the spring washer, so the fastener won’t loosen much.
The use and effectiveness of spring lock washers has been in debate of late,with some publications advising against their use on the grounds that, when tight, the washer is flat against the substrate and gives no more resistance to rotation than a normal washer at the same torque. NASA researchers have gone as far as to say "In summary, a lockwasher of this type is useless for locking."However, a spring washer will continue to hold the bolt against the substrate and maintain friction when loosened slightly, whereas a plain washer will not.
The benefit of spring lock washers lies in the trapezoidal shape of the washer. When compressed to loads near the proof strength of the bolt, it will twist and flatten. This reduces the spring rate of the bolted joint which allows it to maintain more force under the same vibration levels. This prevents loosening.
