I just received a second M.2 SSD that I'm trying to install, but the screw wasn't included in the box and isn't in my motherboard's box. It doesn't help that it looks like an uncommon screw type

The screw socket in question

Where can I find a replacement for this kind of screw? Does this have a name?

  • The only way to 100% sure, since these screws are not always standard, is to check the motherboard's manual or with MSI support

  • That looks like a case side-panel thumb screw, not a motherboard screw. Commented Jul 10 at 12:11

According to Crucial:

A relatively common size for replacement screws is an M2x0.4mm which is also the same screw size that we provide when purchasing one of the drives mentioned above. Be cautious when installing an M.2 SSD not to force this screw into place if it's not the right fit for your system.

  • It does not bother me too much personally but it messes with the SU system. I see good answers being down and nonsense being upvoted, not necessarily my answers BTW. That I find most frustrating. I am not saying this ^ is a particularly good answer, but something that can be found using a 10 second google search. Commented Jul 10 at 23:24
