There are holes in metal that have threads for machine screws. The screws will not screw in because the threads are not clean. I don't know what the problem is (maybe too much paint, maybe a warn tap at the factory, maybe a little of both). All I know is I had to take a tap and run it thought some of the holes before I could put the machine screws in. On the last one it was the threaded holes that hold the key board tray in place. On an earlier one I had gotten (a month or so ago) it was the threaded holes that hold the bar for the two monitors.
