Default Hinge pins - Tip Up -9A

Working on the quick release for my tip up canopy. The plans call out an AN438-16 bolt for the hinge pin, which is threaded I believe. But the drawings show an unthreaded bolt. Am I supposed to grind off the threads? If so should I shorten the bolt? How much? I didn't see any reference to this in the plans.

I know that there are several ways to accomplish a quick release function. I would only be planning to use mine during the build (if/as needed) or I suppose for occasional maintenance. It really seems to me that pip pins would be a much simpler solution. I am thinking about adding access panels on the forward skins, so getting to the pip pins would be a simple matter.

What are other -9 tip up builders doing in this area? Appreciate any input - thanks.
