A 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 substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation. Applicable standards are ASME B18.21.1, DIN 127 B.
Spring washers are a left hand helix and allow the thread to be tightened in a right hand direction only, i.e. a clockwise direction. When a left hand turning motion is applied, the raised edge bites into the underside of the bolt or nut and the part that it is bolted to, thus resisting turning. Therefore, spring washers are ineffective on left hand threads and hardened surfaces. Also, they are not to be used in conjunction with a Flat Washer under the Spring Washer, as this isolates the spring washer from biting into the component that will resist turning.

The use and effectiveness of spring lock washers has been debated, 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.  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.

Spring Washer

Spring washers are often called spring washers in the screw industry. Its materials include stainless steel and carbon steel. Carbon steel is also iron. Commonly used spring washers are M3, M4, M5, M6, M8, M10, M12, M14 and M16. The national standard for spring washers GB/T 94.1-2008 stipulates the technical conditions for elastic washers with specifications of 2-48mm.
