I have a Sun machine with a 13W3 framebuffer output, which is connected
via a Monoprice VGA adapter to my LCD monitor. It works great, but the
ends of the standoff bolts without nuts come together where the VGA
cable meets the adapter; that is to say, the VGA cable's nuts are on the
far side of the shell from its male end, and the adapter's nuts are on
the far side of the shell from its female end.
I'm wondering what I can put between the two to keep the cable from
disconnecting from the adapter. Some searches seem to indicate I want
some 4x40 (or 4-40) female-female (coupling) nuts; does this seem
correct?

"Probably."
I've seen at least two different threadings on similar parts (metal
standoffs for peecee motherboards, male threads on one end and female
on the other). But it seems likely to me that the thread for any
particular connector will be rather better standardized, and one DE15 I
just checked (actually, the DE15 end of a 13W3/DE15 adapter) is indeed
4-40 - or close enough to fool me when tested with a 4-40 nut.

The normal thread for the jackscrews on a D connector is indeed 4-40 UNC.
That's 'UNified Coarse', diameter size 4 with 40 threads per inch.
If you have the male screws in the connector then what you need are some
coupling nuts, threaded spacers, or whatever the suppplier calls them with
that thread. Some PC-builder shops sell them. I've been known to take a bit
of hexagonal rod and drill/tap it, but unless you have the tools for that it is
easier to buy them.

4-40 is the correct size. I would remove the jack screws on one side and replace with
sockets. If you use standoffs the screws May bottom out too soon.

Could you explain that in more detail? I'm not aware of "sockets" except as
the tools that are used for turning hex nuts; is there a kind of socket
that actually gets installed on a bolt?
And I'm not sure what you mean about bottoming out. You just mean there
wouldn't be enough length of thread to fit both male ends securely?

The socket is a metal piece with an inside thread on one end and an outside thread on the
other end. You commonly see them on serial connectors usually on the equipment the cable
attached too.
The bottoming out I was refering too was it you use a standoff you may have too much
exposed thread on the screws. They will meet inside the standoff before the connectors are
properly seated.
