Sealling gaps wing tip skins

I took this photo of a Van's built RV-12iS last week. Not sure if that bolt was replaced, or if the new plans call for a phillips head there, but I thought it was interesting.

A guy in our EAA chapter had a very early 12 when I had just started my build. It used the Phillips-head screws you show in the photo. That’s where I got the idea to use the cap-head screws. So, not sure if he made his own substitution or the earlier plans called for these.

And I also noticed in your photo that Van’s used conical washers on the flush-head screws on the avionics cover, at least some of them 🙂. Interesting that builders are required to EXACTLY follow the KAIs to obtain E-LSA certification, but the factory is able to make minor deviations?
