Same problem here but I caught it before it came off. The factory did not use any washers; about half of the screws on mine were either missing or the head pulled through the aluminum. A couple of them they totally missed the aluminum when they drove the screws in. More high quality craftsmanship! I fixed all of mine last fall.
