Wearing my "long time since I did this" hat.
I have a connector kit to join two water butts.
The diameter of the non-threaded bit is 24mm.
Outer diameter of the thread is 25.64 mm.
So do you cut the hole to be a tight fit (24 mm) and expect the connector
to cut a thread which seals, or do you cut for a loose fit (25 mm or even
26 mm)so the connector just slides in and the seal is on the mating faces
with the water butt plastic?
I'm about to go shed diving again, but the cutters at Screwfix are 25mm
which might be a hint.
Cheers

whether or not the butt has a suitable surface finish to make a seal
with the supplied seal.

A vote for a loose fit and use the washers to make the seal.
All the cutters I can find seem to be 25 mm which may be a tight fit but
will check what the next size up is.
Don't think I can go above 26 mm for the hole and still have enough
surface for the washers to seal onto.
The main upside is that the connectors will be right at the top of the
water butts so a little leakage will not be a major problem, unlike the
taps at the bottom.

with a metal plumbing fitting in a thick enough thermoplastic tank you
can get away with using the fitting as a "tap" in an undersized hole,
especially if you have a back-nut for extra security. A sealing washer
may not actually be necessary, especially if you put a smear of sealing
compound on the threads and the internal and external faces.

length of thread so that there is plenty of room for a back nut.

I take it you have ruled out a permanent syphon between the two?

Not at the bottom, so they fill and empty in sync?

That is how I do mine. Small lead weights on each end of the pipe.

Getting it started the first time is fun and then every decade or so
after a build up of sludge in the bottom. Weights best off about 6" back
from the end of the pipe. I used clear 1cm silicone piping for mine.

Problem is the material of the butt gets hard in the cold weather. I did
mine when I had one with screwing it in to a tight hole with it coated in
dow Corning eurathane bond. Seemed to last for many years.

Given that various surrey/essex/warwick/tech flanges exist which can be
installed into H/W cylinders from the outside, don't suitable flanges
exist for water butts?

Failure-critical though - one detached/damaged link and all the water goes.
I have 3 butts totalling about 550 li that are top-overflow, with no. 3
draining away from the sheds. No. 1 catches most of the crud by acting as a
settling tank. The gutters are covered by mesh but ash seeds and pine
needles...
In the autumn, when demand is low and the rains are starting, I use the
water from 2 and 3 then empty and clean out 3, repeat with 2 (after bailing
it into 3 if necessary) then bail 1 into 2 until the sediment stirs.
Cleaning 1 is the messy part and it needs a scrub as well. I save a couple
of gallons from 1 in a bucket so that the resident leeches have a temporary
home and the same water.
Usually end up with about 200 li left and 3 clean butts.
