For a project of mine, I salvaged some standoffs from the connectors of some scrapped graphics cards. However the screw that goes into them doesn't seem to be 6-32 or M3. Weirdly enough, I had some screws that were the perfect fit, but I don't have enough. It is a thread size right between 6-32 and M3. I should probably just use some standard MB standoffs, but they're already screwed in and I'm hoping to learn a thing or two.
