Thanks guys for the suggestions.
To appreciate the problem one needs to look at Fig's 7 and 9 in the
K3EXREF manual. There is no room for tools. Nor do I think any kind of
gop is a good idea. (Though if this screw were necessary for grounding
I don't think they would have used a split washer but rather inner tooth
washers)
Upon further reading, the corrections of this module appear to be in
~1Hz steps. I was more interested in something that disciplines the
oscillator in a finer more continuous way.

I've used a little bit of coax seal too many times to count. Stick a bit in

re-building a T-8 Tennadyne Log Periodic with lots of difficult to access

totally inaccessible).

The most useful tool, which I have found for this type of application, is
the simple screw "Grabber". Not only can this tool be used to hold a screw
and washer(s) while starting the thread, but also while removing a screw
and washers. It can also be used to retrieve bits of wire, screws, washers
and other small items which may have fallen into "difficult to reach"
places.
The tool requires only one hand to hold it during use, and is operated by
the thumb of that hand. It is also very inexpensive, about $2, and is
available from most of the major stockists.

You are right that one must be careful to not lose the split lock washer
between the KREF3 and the front panel, but testers didn't find the process
very difficult to do.
What a couple of people who suffered hand tremors reported doing to avoid
that lock washer falling off was to put a small drop of petroleum jelly or
soft candle wax on the screw after placing the lock washer on it. That
kept
the washer from easily falling off while they repositioned the KREF3 board
and started the screw threads into the fitting on the front panel shield.
