Is that actually a galvanized roofing nail?

More like a joist hanger nail.

That's even scarier than it looked from the outside. Held my ~5' fall though..

That looks like the nail from a Star Dryvin bolt.

Star Dryvins.


The two bolts on the left were improperly installed with the sleeve underneath the hanger and only the nail holding the hanger onto the bolt. This is a very weak configuration and is not recommended. The bolts in the middle are properly installed Star Dryvins with the sleeves on the outside of the hangers. BTW, the middle, top bolt is a 1940s to 1950s Star Dryvin without the lead band around the sleeves.

This bolt seemed to be installed correctly. The sleeve was holding the hanger on. There was very little corrosion. I'm not surprised it held a fall. I also wouldn't have been surprised if it didn't. It was very easy to remove.

The bolt has been replaced. If you stick clip, this is no longer X rated....
