Ok found the screw that goes to the Strix. I just got really lucky. The screw I was gonna use, is what the other NVME on the mobo is using and it's fine.
The strix threw me for a loop because the screw that goes with it has a cut out in the center where you thread the yellow semi circle through and the only thing I can figure is it acts to offset the M.2 and prevent it from hitting the bottom of the Strix. But the regular M.2 screws I have don't have that because their not needed on most mobo.
