A toothed washer, also known as a serrated or star washer, is a hardened fastener component placed beneath a bolt head or nut to prevent the fastener from backing out over time. The serrated edges bite into both the fastener and the mating surface when torqued down, creating mechanical resistance against loosening caused by vibration, thermal cycling, or dynamic load shifts. In generator and welder applications like the DLW series, where continuous engine vibration is present during operation, a worn or missing toothed washer can allow critical fasteners to back out, leading to component misalignment or electrical connection failures.
