Rivets

Tonight I started working on the 1st of 2 small practice projects in the Van's Aircraft Practice kit and I got thoroughly confused on which rivets to use. A standard nomenclature that is used that is pretty easy to follow, but the bags of separated rivets aren't identified clearly by that nomenclature. "Hey Siri, what is a AN426AD4-4?" "Hey Siri..."

At this point I had been in the shop a few hours and needed something to drink and a biological break so I figured it was better to fall back and regroup. Live to fight another day, so to speak. So far I am enjoying this learning experience and seeing parts come together.
