Makita 251441-5 Spare Part - FLAT HD SCREW M6X22 DS4010
Original Makita flat-head chuck screw — part 251441-5 — designed to replace the small but critical fastener that holds the drill chuck/spindle assembly in place on compatible Makita corded drills. It’s a genuine Makita component made to the same shape and fit as the factory-installed screw so the chuck seats and locks as intended.
Key specifications (metric): M6 × 1.00 thread with a 22 mm threaded length (overall length commonly listed ≈25 mm); left‑hand thread; flat (countersunk) head with a slotted/hex drive profile; head height ≈4 mm and head diameter ≈9.4 mm; steel construction with a dark/black finish. These dimensions make it the correct replacement when a stripped, missing or damaged chuck screw is the cause of a loose chuck.
Example models the 251441-5 is used on (representative, not exhaustive): Makita DS4010, DS4011, DS4012 series drills and older 6302 / 6302H / 6303 / 6303H corded drills (also appears on certain 6013BRK / related variants in parts diagrams). Check your tool’s parts diagram to confirm the same screw number appears at the chuck/spindle location.
Sold individually — a small, inexpensive part that solves common chuck-retention problems and lets your Makita tool perform safely and accurately again.
