Original DeWalt plain washer — part no. N016823.

Flat metal washer designed to seat under a fastener in DeWalt drill/impact-driver assemblies to spread clamping load and protect the housing while keeping screw alignment secure during reassembly.

Listed on DeWalt parts diagrams for a number of drill/driver and impact-driver models — for example DCF885B, DCF886B, DCF887B, DC825, DC827 and DC835 (confirm against your tool’s parts diagram for exact fit).

Sold individually and useful to have when replacing a missing or damaged washer to restore correct fastening — a small but important DeWalt parts item to keep with other power tool parts.
