Where can I purchase the screws for battery?

Jesse Garcia in that case it is not the screw that is a problem but the standoff. Since the screw broke off on the inside of the standoff, there is really no way to remove it. It should not cause an issue for as long as you know that it may be tough to replace the next battery. The upper standoff at the middle of the logic board holds the screw for one side of the dock flex connector cover plate. The lower standoff helps to hold the logic board down and provides the screw for the battery flex connector. That will only be an issue with the battery flex connector during battery removal.
