My ancient Tyford close coupled ceramic toilet cistern is held down to
the pan by two butterfly nuts that screw on to Brass Bolts extending
underneath the cistern.
Being about forty years old the diameter of the bolts are 'between' the
common 5M and 6M size. (i.e. bolt will not go into 5M nut and a 6M nut
is too big).
Would anyone know what kind of butterfly nut size and type of thread I
should be looking for? Also how best to try to get hold of a no longer
common sized one. Thanks.
Messingers still there?
Also Mackays in Cambridge...
And a few others
I assume you mean M5 and M6, so we are looiking for around 5,5mm
suggests that 7/16" Whitworth is a good place to start and te other
possibilitity is UNC. I doubt that UNF would be used on a bog seat!
gives #12 UNC as the size.
You could probably ID which it is (UNF/UN/Whitworth) by counting threads
per inch and looking at the thread profile. Whitworth is rounded and
UNF/C is flat topped.
Hmm. It looks like actualy BSF/UNC/M is more likely than whitworth
Suggest you look here.
If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such
I'm sure \i've seen unc unf whit and ba around on adverts quite recently. I
think perhaps if it has to be the same, then the first job is to find
somebody with a set of thread gauges to see what you are looking at.

Cathing up, Messingers sold out to Buck & Ryan but closed when tehn lease
ran out. The premises were taken over by Cath Kidson, B&R lost their
Tottenham Court shop due to rebuilding and moved to Southampton Row. They
also had a tiny franche in Selfridges. They vanished about 4 years ago,
from KT24 in Surrey, England

There is a shop in Lincoln at 5 Csketgate that looks very
interesting, although I've never been inside but would
definately check it out if I wanted something special.
It's called Musgrave (Tools) & Co.Ltd and has been around
