Do the non-flush screws help with longitudinal stability?
Yes, of course. Those of us with powerful
RV's need more feathers on the arrow
Kidding aside, let me make a case. I use AN526C's with nylon washers for most glass, just because it's more durable long term. Countersunk glass always seems to end up with a wallowed out knife edge in the bottom of the hole, and chipping at the surface. A straight hole is stronger, and the nylon washers make life easy for the paint.
Admittedly it would not make much difference on something like this lower strip fairing, a part not heavily loaded or removed very often. On the other hand, I have a row of screws down the long cowl seams. After 1000 hours of heat and vibration, and being in and out a zillion times, the holes and paint remain in good shape.
