Does orientation matter with this style of trim pot? As in, does it matter if I flip them around going into a PCB?

My DMM testing shows that the pot changes the resistance from each end to the middle, which makes me think it doesn't matter which way they go.

Electrically no different, as its a linear pot. Physical behaviour will be swapped around.
...the position of the adjustment screw will be at the other end.
...the clockwise/anticlockwise behaviour will be swapped, with respect to the circuit its put in.

Yeah, thanks, this is exactly what i thought!
