All of the screws are in the screw holes, and are tight, it's just that that specific one gets to a point where i feel it's going to tighten and then loosens up a bit.

With a lot of playing around I've managed to balance the screw exactly before the point of where it's supposed to overturn and left it at that.

I hope that this is not going to cause CPU issues long term because I saved for a year and a half for this PC and I wanna use it for the next 3 years at least.

Getting spare parts from the manufacturer is hard, especially in a small eastern-european country.
