I was doing my Sunday morning car wash, and wiping down the engine bay. I accidentally hit this little plastic hex bolt and kind of knocked it loose. As I was putting it back on, I realized it's used to adjust the amount of "gap" between the top of the bumper and the hood. You can tighten it down by hand. It seems to be a stop for how low the middle of the hood rests. I did about one turn, and the hood sits more flush with the bumper
