Bath Fan Humidistat Set-Screw Dial Knob
Replacement dial knob for humidity-sensing bath exhaust fans. When the original snaps off at the shaft, the sensor module is usually only sold whole. The 32 mm fluted knob has a 6.5 mm blind bore and a radial M3 heat-set insert (4.0 mm bore) for a set screw, so it clamps on round or D-flat stubs up to 6 mm without needing the exact OEM shaft size. A pointer fin shows the % setting, and the hollow back keeps it light and clear of the faceplate.
