Good info. If you look at the inside of the pipe, it's anything but completely smooth, particularly with the ridges from the telescoping plastic. The portion that the bolt head would rest would be contained within the recessed area, not protruding into the air channel. Of course, a flat, and round bolt head would be better than a hexagonal one that protrudes.
