These special screws are very nice. I just bought the panels and screws from Menards. The manufacturer is Amerilux.

Normally you need to pre-drill the hole slightly large than the screw so the panel can move a little for thermal expansion and contraction. The special screws I bought have a special feature, i.e., when screwed in, the top part enlarge the hole a little so no pre-drilling is required.
