Hosco KB-140S Potentiometer Knob, sharp edges, small, black

Premium knob from Japan.

Potentiometer Control knob, small

Press-on mounting without any set screw.

Knob hole is 18 toothed knurl and is designed to fit metric potentiometers with 6mm diameter shaft with 18 teeth knurl. If your potentiometers have shaft cut into two parts (cut taking 2 teeth away), you will likely count only 16 teeth. That is still the correct potentiometer for this knob.

We do not recommend it, but if you are in a jam (pun intended), you can push this knob by force onto US Inch potentiometer with 1/4 Inch (6.35mm) diameter shaft with 24 teeth.
