Double Coiled spring have been in use from many years. Spring washers, sometimes called disc springs, are a subtype of washers. Spring washers are employed in applications where assemblies need a part to take up play, eliminate rattle, maintain assembly tension, compensate for expansion or contraction in materials after assembly, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.

Spring washers also called split lock washers, provide a vibration resistant function, they consist of ring split at one point and bent into a helical shape, this causes the washer to exert a spring force between the fastener's head and the bearing face which maintains the washer hard against the face and the bolt thread hard against the nut or threaded hole, creating more friction and resistance to rotation.
