Black Metal Knob - 14x24mm
Knobs are a great way to finish off your project and make it easier to adjust the level of your death ray. This knob mates to a 6mm (+/- 0.3mm) shaft. The knob slides onto the potentiometer and holds tightly with a strong friction fit.
The main body of these knobs is metal with a plastic insert. The outside is knurled for precise adjustment.
