We use aluminum interlock structural rivets. They only go down to 3/16". They're probably overkill, but they have good clamp-up and hole filling. And Allen Gregory from 3847 pointed out that they use the same drill as a #10-24 clearance hole.... So if you standardize on 3/16 rivets and #10-24 screws, you only need one drill bit for a lot of your construction. 3847 is doing that, and it sounds like a nifty idea to me.
