Milwaukee Chuck Screw
Model Number: 05-88-1440
The Milwaukee 05-88-1440 is a genuine OEM Chuck Screw for use in compatible Milwaukee drills and driver-drills. The chuck screw passes through the center of the chuck and threads into a tapped hole in the spindle to retain the chuck on the tool. Many Milwaukee chuck screws use a left-hand thread — because the drill spindle rotates clockwise during forward operation, a left-hand thread causes the chuck screw to tighten rather than loosen under the torque of normal forward drilling and driving. Milwaukee offers a large selection of chuck screws with different thread specifications, sizes, and drive types across its drill and driver lineup — always verify the correct part number from your tool's service parts diagram before ordering, as ordering the wrong chuck screw can result in improper retention or a screw that backs out during use.
Using a genuine Milwaukee OEM chuck screw ensures the correct thread specification, length, drive type, and head geometry for the spindle it serves. Non-OEM chuck screws may not match the original thread direction, class, or length, leading to improper chuck retention or loosening during operation. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct chuck screw for your specific unit.
