Milwaukee 10-32 Left-Hand Thread Chuck Screw
Model Number: 05-88-1426
The Milwaukee 05-88-1426 is a genuine OEM 10-32 Left-Hand (LH) Thread 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. The 10-32 designation identifies this as a #10 diameter screw with 32 threads per inch — a fine-pitch imperial thread specification. The left-hand thread is a critical design feature — 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. A stripped, missing, or incorrect chuck screw that cannot retain the chuck on the spindle requires replacement to restore secure chuck mounting and prevent the chuck from detaching during use.
Using a genuine Milwaukee OEM chuck screw ensures the correct 10-32 left-hand thread specification, drive type, length, and head geometry for the spindle it serves. Installing a right-hand thread screw in place of this left-hand thread screw will cause it to loosen and back out during normal forward drilling 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.
