You don’t have a screwdriver? M.2 screws don’t use any sort of special screw head. They’re almost always a regular phillips screw size #0 or #1, maybe even being cut for a flathead to work as well.

I don’t think I’ve ever even seen a drive come with a screwdriver.

The M.2 screw itself usually comes with your motherboard. But even then, they’re fairly standard. The specification is for a M2-0.4 x 3mm screw.
