Tie a small nut or washer to the other end so it drops straight down instead of swinging all over the place. Also works great for fishing nuts and bolts out of a dropped engine bay.

Oh wow, I used to just lean mine against the garage wall and call it good. Then I had the same problem as you and it cost me a whole weekend, so now they live flat on a shelf inside the house where the temp stays steady. Heat and leaning are the two things that killed mine.

Whoa, hold on, no joist hangers at all? That is wild to me because rim joists carry a load and end nailing into the band is just asking for trouble down the road. And the part that really gets me is the guy saying the inspector doesn't even crawl under there, like that is just accepted now. I get that inspectors are busy and can't see everything, but skipping the crawl space on a framing inspection is a big deal. If that house ever has a floor sag or a squeak problem, nobody is going to remember the guy who nailed it flush. That whole street is a callback waiting to happen.
