I ordered M5x12mm screws for stem to fork tube tightening along with nut because my stem came with those nuts - if your stem doesn't have the nut then you need M5x16mm, two M5x40mm + two M5x25mm for handlebar to stem tightening, M6x30mm flat top for stem cap, M5x16mm for bottle holder and just to fill the holes on the fork.
I believe almost all bikes have same measurement because same screws fit on my Cannondale and Giant too.
