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

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.

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.


And you can get it cheap from the missus or the discount store.

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.
