Update - the cheap and shonky nylon wingnut things underneath have partially
disintegrated.
The 'washer' part which presses against the porcelain has crumbled.
However, if given lemons make lemonade :-)

It turns out that if you trim the nylon wing nuts down, removing washer and
finger grip wing bits, you are left with a tapered nylon plug which screws
up the M6 stud to hold the top washer in place against the brass plate, and
fits snugly into the hole in the porcelain.

Marginally too long, but rather than cut it down I am going to get an M12
washer to go with the M6 washer to spread the load, and then screw the whole
thing together and hopefully have a stable bum at last :-))

Take care if using metal washers. That area gets an aerosol spray of
acid pee around it, and will corrode. I noticed B&Q are selling a kit of
plastic cone washers designed for your purpose. I find that using
silicone sanitary sealant to glue the flat part to the pan is pretty
effective.

You can make a handy tool for positioning and tightening the awkward
wing nuts by cutting slots into the end of a short length of 15mm copper
pipe. Steel would be more durable but 15mm copper is likely to be to
hand.
