There are nails at the center of the free throw line. Every hardwood basketball court I have ever played on has them. In fact, tt is the first thing I say to find for anyone I teach to shoot free throws. Usually the nail is covered by a thick layer of lacquer and paint so I've never thought it could come up. I wonder if it is possible that was the nail.
