For Mitch Locke... Why are 1100-08 plate nuts (countersunk) used here instead of 1000-08 plate nuts? The spar flange is countersunk to accommodate the dimpled fuel tank skin with 8-32 flat head screws. The 1100-08 plate nut creates a void between the flange and the plate nut threads.... not good. Not to mention, the 3-3.5 rivets are too short to create a good head on the 1100-08 due to the thickness of the plate nut. I installed the 1000-08 plate nuts in 2 of the locations and they work perfect, with no void between the spar flange and the plate nut threads. Can you comment?
