My CTC appears to have 5mm cheesy screws so I'd like to replace them. The problem is I can't find any 5mm screws, everything turns up as 8mm. I ordered couplers and screws but it's definitely 8mm, not 5. So my question is, are there good 5mm screws out there and if not, it looks like I'm going to have to replace the bearings and the mounts for the screws too, right?
