Hello, I recently had a problem with my case and wondering if I should be worried about this situation. I have a fractal design meshify c and the power supply bolts onto a bracket instead of the base itself. That went smoothly but then it bolts to case with 2 thumb screws and I noticed one fastens all the way and tightens up but the other one keeps screwing and doesnt seem to tighten up. It doesnt semm to back out neither. So is there somthing I can do to fix this so I know I have a fastened psu?
