Application Summary AI generated
This standard specifies the dimensions, technical requirements, and marking methods for heavy-duty single coil spring lock washers. It is applied in mechanical assemblies where high clamping force and vibration resistance are critical, such as in heavy machinery, automotive drivetrains, and structural bolted connections. The washers prevent loosening of fasteners under dynamic loads by exerting continuous spring tension.
