Going Nuts

Well, nut...singular...or maybe, I'm just off my nut...either way is good, so long as I'm not losing my marbles!  A lonely hex nut, likely from a vehicle, out in the desert.  Don't worry, though, they always put in extras.  I know, because I generally have leftovers after any automotive maintenance project.  Before long, I'll have enough to make another car!  8^)
