What screw sizes do I need to install my SSD and HDD in my case

[ThrashTilDeth]

I have a NZXT s340 case, a WD Blue 3.5" 1.0TB and a Sandisk SSD Plus.
I have several screw packets, but I'm unsure which ones I should use for these drives.
The SSD screws in from the bottom and I'll be screwing the HDD into the bay from the sides.
I have three bags of screws. Can anyone tell me which goes where. Don't want to mess up the threads!
1 bag of 6-32 flats
1 bag of 6-32 hexagons
1 bag of M3*5 flats

all 3.5" hard drives are 6-32, pick whichever head you prefer

nearly all 2.5" drives are M3 - if you're NOT sure, start with the (smaller) M3 and if it feels a bit sloppy, only then try a (larger) 6-32. the 6-32 is fatter so forcing it where it doesn't belong WILL strip threads. the M3 is thinner so no risk of damage if you start with that.

LOL. Too much precision for me. I just reach into my screws pouch which I have accumulated through the years and go, this one, no, too fat, OK the smaller one, nope too loose, OK let pick 10 and see which one fit best, I know there are in the pouch somewhere!

pfft! there's only 3 sizes as far as i know:

6-32 is the main larger one for 3.5" drives and most case panels, mobo standoffs, PSU, etc
M3 is the smaller one for 2.5" drives and some case panels (usually if a case panel starts with M3 and it gets worn down, using a 6-32 snugs it right up)
2-56 or something in that range for really small stuff like slim-DVD drives.
