Milwaukee M8 x 15mm LH Hex Head Machine Screw
Model Number: 45-04-0016
The Milwaukee 45-04-0016 is a genuine OEM M8 x 15mm Left-Hand Thread (LH) Hex Head Machine Screw for compatible Milwaukee power tools — a specialty fastener with left-hand thread that tightens when turned counterclockwise, used in Milwaukee tool assemblies where the fastener's thread direction must oppose the tool's rotation direction to prevent the fastener from self-loosening under normal operating torque. Left-hand threaded fasteners appear in specific positions on rotating assemblies — most commonly on the left side of tools with bidirectional rotating components where the spindle rotation in normal forward operation would tend to unscrew a right-hand threaded fastener over time. The left-hand thread ensures the operating rotation tightens rather than loosens the fastener during normal tool use, maintaining the assembly's structural integrity without the special locking hardware that right-hand thread fasteners at this position would require.
Using a genuine Milwaukee OEM left-hand thread fastener ensures the correct M8 diameter, 15mm length, and left-hand thread pitch for the specific Milwaukee tool model — substituting a right-hand thread fastener of the same size would not provide the self-tightening thread engagement this position requires, allowing the fastener to work loose during tool operation. Always verify your specific Milwaukee tool model number and serial number at milwaukeetool.com before ordering this specialty fastener component.
