Milwaukee Rip Fence Knob
Model Number: 43-30-5581
The Milwaukee 43-30-5581 is a genuine OEM Rip Fence Knob used across Milwaukee M18 circular saws. The rip fence knob is the threaded knob that locks the rip fence, or edge guide, to the saw's shoe: the operator slides the fence to set the cut width, then tightens the knob to clamp it so the saw tracks a straight, repeatable rip parallel to the workpiece edge. Threaded into the shoe, it holds the fence firmly against cutting forces. Because it is tightened and loosened on every fence setup and takes clamping load, the knob can crack, strip, or wear so it no longer holds, at which point the fence shifts mid-cut and the rip wanders. Replacing it with the genuine Milwaukee OEM knob restores secure, repeatable clamping of the rip fence, where an off-spec knob may not thread correctly or hold the fence under load.
This rip fence knob is used on more than one Milwaukee M18 circular saw. It is identified as the Rip Fence Knob, Figure 40 on the 3026-20 M18 FUEL 10-1/4 in. Circular Saw (bulletin PN0008141), and Figure 37 on bulletin PN0005520, where it clamps the 49-22-1005 rip fence, and Milwaukee specifies applying a thread-locking sealant to the knob thread on assembly. The rip fence itself (49-22-1005) and other surrounding parts vary by saw model and are sold separately, so confirm the correct parts for your exact saw from its own diagram. Because Milwaukee specifies service parts by serial number as well as catalog number and this knob spans several saws, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering to confirm 43-30-5581 is correct for your saw.
