Which bolts are they? I don't think I've ever seen a cistern that
had such a thing. Aren't they always attached to the fabric of the
room separately, then the only thig with "bolts" is a steel clamp
plate that's pulled down onto the pan so as to crush the doughnut
and squirt it sideways, thus sealing against the syphon outlet.

Quite common. You get both the 'steel plate design and the 'holes
through bottom of cistern' design. The latter has 2 SS bolts & cone
shaped rubber washers. They go right through the cistern & pan and
are done up underneath.

Yes I know.

Quite often seen in cisterns that have been supplied with a plastic
liner. All fine and dandy - except that the fixing bolts go through the
liner as well as the cistern ...
