I too had a problem with a bolt coming out of the bathroom floor. It finally came through by a guest stepping on it. Turns out it is a very large wood screw, I have no idea what it holds but I put some thread lock on it and screwed it back down with a large srewdriver, turning it tight with a crescent wrench. I then repaired the hole in the floor with some clear vinyl repair adhesive. When it came through the floor it kind of formed a flap in the vinyl. I just pushed it down and you can hardly see it.
