Milwaukee Screw Bar Assembly
Model Number: 45-84-0140
The Milwaukee 45-84-0140 is a genuine OEM Screw Bar Assembly for use in compatible Milwaukee tools. The screw bar assembly is the threaded spindle or rack assembly that converts rotary handle motion into linear axial travel — used in drill press quill mechanisms, pipe threaders, and bench tools where a threaded spindle advances or retracts a working component in response to operator rotation of a handwheel or handle. The screw bar thread must maintain precise pitch accuracy and smooth low-friction travel to ensure consistent, controllable feed rates throughout the full travel range of the mechanism. A worn, damaged, or cross-threaded screw bar assembly that introduces binding, backlash, or irregular feed motion requires replacement to restore smooth, accurate linear feed control.
Using a genuine Milwaukee OEM screw bar assembly ensures the correct thread specification, bar length, and mounting geometry for the feed mechanism it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct assembly for your specific unit.
