When mounting 2.5" SSDs, the correct screw size is a m3 with 5mm length (m3-5), what is the correct head shape?
I ordered some flat head screws to mount SSDs in a Athena Power BP-SAC1425AVL12 (4 x 2.5" in 1 5.25" bay.
When I mount the drives in the trays, they stick out from the bottom of the trays and make the trays very difficult to remove.
Am I crazy (I am but you cant tell from the internet) or is there a better screw heat type to fit in these types of applications?
I’m not sure there’s really a “correct” type of mounting screws for SSDs. It probably varies from one case/enclosure to the next, but I think what you’re looking for are called wafer head screws. The screw head is just a flat disc so it shouldn’t extend out much past the edge of the drive tray.
Flat head screws are usually what you use when you want a completely flush mount, but then you’ve got to have tapered screw holes also, and I’m guessing since they stick out this drive cage doesn’t have them.
The correct screw head is whatever fits in the case, the drive doesn’t care
That’s why it’s usually the cases that come with the screws, not the drives. Some drives come with general purpose screws just in case, but that doesn’t mean they are “the right ones”, just that they fit when needed.
Don’t overthink it, just take whatever screw fits your case and is an M3-5
These screws don’t fit flush, but I guess the higher section in the middle must be what is making the drive drag more than the screws are. It’s hard to take a good picture to show that. Thanks for the help @redocbew and @mihawk90 !
It just seems rougher than it should be. I guess cramming 4 - 2.5" drive trays is a pretty big ask for a 5.25" bay.
What I have is 5mm, not 3mm, and it seems ok. I swapped for m3 - 4mm screws and no difference on the height.
YMMV but these seem fine for a tight chassis like this.
Hell I have calipers, and I get the “has goddamn everything” packs of screws. Because eventually I’m going to run across something they needs something special.
For example, I prefer big fat tall screws for securing the motherboard, however my old taichi x399 had one location where those didn’t work and I needed a more traditional small form.
Over preparation right now saves me $10 and a few days of waiting later.
