9mm Alpha Potentiometers with Nut and Washer. No "Anti rotation" tag. Shafts are 6.35mm round. I chose these pots because they are durable, and have a smooth travel. If you wish the 9mm alpha potentiometer, you can screw the knob on closer to the panel, and further away for a looser turn. Nuts and Washers are included, but bagged separately to save you time. Here is the 9mm Alpha Potentiometer Data Sheet.
