It slides over the spindle and features a tab that locks into the spindle keyway, preventing the inner bearing adjustment nut from backing out while the vehicle is in motion. It's commonly replaced during brake jobs, bearing repacks, or if the existing tab or washer has become worn or damaged. This particular model includes a set screw which acts as a stop for secure fitment.
