My motherboard has 2 M.2 NVME slots but only comes with one screw because the manufacturer somehow decided it made sense. They work great as intended and I now have a few extras if I need them. They don't seem to be easy to find in brick-and-mortar stores or other online stores (in my personal experience). I found them here, got them quickly, and got them when I needed them to complete the build.
