The DeWalt 90624303 Retaining Ring is an official replacement part (often described as a washer). It is positioned beneath the chain cover next to the guide bar on various cordless chainsaws. It works alongside a screw to hold the cover and bar securely in place, keeping your tool safe and functioning properly.
