I would like to be able to tell by colour if a screw has turned - does
that exist?

Low-strength/removeable...

Maybe a kind of varnish?

Fingernail polish works nicely as both a thread locker that will allow
the screw to be removed easily without extra effort, and it will show
if the screw has been removed or moved.

Works better than "locktite" for gun applications. And you can get it
cheap from the missus or the discount store.

Have a good story ready for why you need it. I've found it in all the

A dot of fingernail polish on one side of the head and the

turned.

I marked the caliper box to prevent storing it upside down and letting
the batteries fall out and short against the case. I set the case
down once and saw a tiny puff of smoke. Whoa! When I popped it open,
I found the battery trying to arc weld the case of my new digital
calipers. A dot on the top cover reminds me to store it upright.

I have pink metalflake and clear from Dollar Tree. I put it on a
screw to remind myself that I've had the lid off that particular piece
of equipment.

The problem is I can only see (easily) the threaded end of the fastener,

the eld I can see, but the screw does do project into the larger section.

I want to put a drop in the well, and be able to look later to see if the
screw has turned, so it has to stick to the screw and the hole and change
colour if it's been broken.

Time for some experimentation...

Used it a lot when I did electronics repairs. I used a real ugly green.
Made it easy to tell if I had worked on an item before and if the part
had been touched by someone else.

For the OP, I've not seen a single coating that changes that way, BUT if
you put a small dot of the paint at the junction of screw/part. it would
show up if the screw was moved because the coating would be broken and
shifted.
Another option would be a simple index mark, like using a sharp scribe
across the end of the screw and up the interior of the hole.
Misalignment means the screw has moved.

Try a pinstriping brush or fine artist's paint brush. They're thin
and long. It that's still too large, dip a straightened paper clip
into the nail polish and poke that down the little hole to get to the
fastener.

I was dabbing the color of the removed wires directly on the rivet of
the Faston tabs, since the wire number labels aren't all close to
their terminals.

The Navy must have unloaded their surplus grey paint on the Army after
retiring the battleships because it was our standard interior and
equipment color too.

Fingernail polish works nicely as both a thread locker that will
allow
the screw to be removed easily without extra effort, and it will
show
if the screw has been removed or moved.

Works better than "locktite" for gun applications. And you can
get

A DNA analyzer is a tad bit more expensive than a Geiger counter with
a pancake probe and you're certainly not going to carry the analyzer
out into the field.

I mix my isotopes in a specific ratio so if an argument ever arose
about the authenticity of the radioactive dot, I simply analyze the
dot with my gamma spectrometer to look at the ratios and the relative
decays.

Another option that is becoming more and more practical is to mix a
specific ratio of elements, preferably metals, in the dot. Then use
one of the hand-held laser ablation atomic absorption spectrometers
that scrap metal dealers use to determine the composition of an
unknown alloy before bidding on it. Only problem is they cost about
$25k currently.

I have a friend who had a large scrap metal operation. He has a gun.
I can sometimes talk him into letting me shoot an unknown. He tends
to hover when I'm using it.

Like most discussions on Usenet, this one is getting rather esoteric.

If I had a serious tamper problem, I'd have a chemist friend supply me
with some photochromic paint he developed. It starts out bright
orange but rapidly turns brown. The authenticity proof is to break
the seal, preferably with a video camera looking on. The interior
will still be bright orange and will darken before your eyes. If the
tamperer has tried to hide his tampering with brown putty or paint,
it'll be brown even when first broken.
