I think it's specific to the antenna switch. Most of the other knobs have a clip that holds them on to a shaft the has a flat on one side. The antenna switch shaft is completely round with just a small flat spot for the set screw to seat.

The switch is spring loaded to a centered position. So you push in or pull out against the spring to raise or lower the antenna. So I assume that is why the shaft is more stout and requires the set screw vs the simple spring metal clip.

The switch shaft also appears to just turns, but has no stops or indents. So I assume that is just to prevent large hands from twisting off the knob.
