My motherboard has 2 M.2 NVME slots but only comes with a locking screw because somehow the manufacturer 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). Found them here, received them quickly, and received them when I needed them to complete the build.
