A screw that is stuck

Hi!

I’ve bought a Rover V2 from you a couple of weeks ago. I have had major difficulties connecting the metal “pinches” to the wires (connecting to the motors) - but I think i managed. Probably will have to tape a bit. Anyways - my problem now is that one of the screws that i’m supposed to connect to the tips of these wires is completely stuck! And I dont want to use to much force - in case the soldering and the whole thing falls off!

Do you have any ideas of what I can do?

Can you provide a clear image of the area you are talking about? We have never encountered this situation.
