Just get an M.2 screw from Amazon. I got three Inspiron 3670 PCs from Best Buy recently. They all had the standoff screw, but not the M.2 screw that screws into the standoff. So I ordered it from Amazon and now my Mushkin Pilot M.2 NVMe drives are secured properly in each Inspiron 3670 PC. This is the M.2 screw I ordered from Amazon. The M.2 screws worked great but the standoff that also came with it was not used.
