Installed three MaXXair's several years ago. First, an "original" onto the sheet metal flange of the bathroom vent. I used the stainless machine screws, nuts, and related washers provided in the small parts kit. I had misread the product literature and was disappointed the "original" did not come with the quick access hardware that's standard on the MaXXair-II's. That said, no vent cover issues of any kind with that one.
The two others were MaXXair-II's onto Fantastic Vents, which have thick plastic flanges. It's been awhile, but I don't think they came with self-tapping "sheet metal" screws as an alternative to to the machine screws. It took me a VERY LONG time to get far enough into the Fantastic units to install the nuts and washers. From what I hear lately, self-tapping stainless screws are the hot setup for plastic flanges. Just drill the hole and drive the screw.
This is where it gets odd. One of the two MaXXair-II's is sitting pretty. The other has worked loose a couple times. I removed it in a rest area last month so we wouldn't totally lose it. I found one machine screw, rest gone. Selected self-tapping stainless screws that would catch well in the worn machine screw holes. I think they're #12 because I went up with #10 and didn't like the way they didn't seem to tighten solid.
