Aerotights generally last until they go rusty.

I was thinking about that as well. ;-)
I thought of a female hex the same size as the nut, welded to the
angle and a retainer over the top to stop the nut falling out ... or
just tapping a M10 thread in a little bit of 10mm plate and tacking /
bolting  that on there. ;-)
However, it's quite handy to be able to rotate the nut as then you can
set the position of the eye and then nip it up. Or, if I want to make
the eye movable it might be easier to let the assembly rotate without
the nut undoing.
In hindsight I also quite like the simplicity / flexibility of using a
std nut / bolt assembly. Easier for field repairs or mods etc.

 Using two countersunk machine screws from the top of the angle
before fitting it to the trailer.
