I was curious about that too. They look like Torq-set to me, being that the slots are offset from the center of the screw. If that’s the case they’re shouldn’t be any cam out at all.

In either case the fasteners that were stuck appear to be Hex head, and the phillips looking fasteners just held a protective cover in place (?)

I would imagine NASA would know better than to use Philips for anything lol.

By the way there is a link on the page to more images of the assembly
