Genuine Makita tapping screw, part no. 266374-1 — a self‑tapping M4 × 25 mm screw designed to secure housings and internal assemblies on Makita cordless tools. Reliable fit to Makita’s factory parts diagrams and used where a 4 mm diameter, 25 mm length tapping fastener is specified.
Why this is useful for repair: the screw’s self‑tapping threads cut into plastic or thin sheet metal housings so you can reinstall covers, motor mounts, or nameplate assemblies without modifying the tool. It’s the exact Makita part referenced in multiple exploded parts diagrams, so it replaces the original fastener called out by the manufacturer.
