No. The metal piece through which the screw sits is on the *lid*, not
the
outer frame. (There is a narrow gap between that piece of metal and the
outer
frame, which can just be seen in the photo.)


In that case, what are the screws *for*? If they don't hold the lid onto
the frame, do they simply blank off the threaded holes - until such time
as they are replaced by lifting eyes?

I'm not sure that you understood what I meant about the outer frame. The
part which is concreted into the ground will have a flange all the way
round which extends under the edges of the lid by an inch or so to
support the lid - which would otherwise fall into the hole! My hunch is
that the threaded holes are in that flange, with plain holes in the lid
itself. I don't see how you can be certain that that is not so without
taking it apart because the relevant bits are simply not visible.


a visit to a friendly builders merchant might be sensible. See if you can
find your cover on his shelves.
