Knobs supplied with grub screws and allen key for attachment
9.5mm Recessed top to place circular labels
To install, slide something thin and plastic under your existing knob to pop it off (or a small spoon works quite well). Align the grub screw with the flat part of your encoder shaft and tighen just enough for a firm fit, overtightening will certainly dent your encoder shaft and if you go crazy will damage it.
