Thanks Phil, but that's not it.
This is what I'm talking about:
http://www.dimensionengineering.com/appnotes/vibration_meter/multimeter_internals.jpg
Bottom right corner, just the bare 4mm turret/tube that solder
directly to the PCB.
(BTW, that took a ridiculously long time to find a photo of, my Google
mojo must be way off today)

 **  Nothing stops you using the two nuts, one above and one under the PCB 
to achieve the same result.

 Solder them to the pcb as well if you like.

Thanks, but that ain't it.
As posted elsewhere in the thread, this is what I'm specifically
after:
http://www.alternatezone.com/images/BananaJackPCB.jpg
The solder type with just the bare 4mm barrel, as used in multimeters.

I'm aware of the many screw, press fit, and other mounting
alternatives, but that's not what I'm after in this case.

Thanks.
Dave.

This claims to be pcb mount 4mm socket but I can't see how it provides reliable
mounting.

You could try to find a piece of 4mm ID tube and just solder it in place. 
Check the hardware stores or hobby shops for brass tubing.

Good Luck!

I was thinking a *really* crappy solution would be a 4mm through-hole
in the PCB :)

PCB-mount banana sockets instantly bring the word 'fracture' to my mind...

Taking a new look at the PCB 4mm socket in the link I gave to to Rapid seems to
infer that it must be mounted in a 4.8mm diameter plated thru-hole. Soldering on
both sides (and inside the thru-hole) would ensure maximum rigidity and freedom
from cracking.

Solder is NEVER suitable as a mechanical joint.

Do you always glue down SMT parts before soldering?

Tell that to Fluke who have used PCB mount banana sockets from day one
in their famous 70 series meters.
Many other manufacturers too.

What utter crap!

How do you think almost every electronic component is fixed to a PCB? If solder
wasn't a suitable mechanical joint then all those electronics enginers have been
seriously misguided over the past 80 years.

I don't think things have changed since I was tought the importance of soldering
in electronics back in the 1950's.

The purpose of soldering is to provide;
1)  mechanical support - to physically hold components together.
2)  electrical support - to ensure reliable electrical connections.

If you are referring ONLY to components which must endure some regular physical
stress (such as plugging in a 4mm banana plug) then for sure, extra strength is
required. I wouldn't call this particular action to be particularly stressful on
the soldered joint BTW. Also, if these TruConnect 4mm sockets from Rapid are
correctly mounted in a plated thru-hole of the correct diameter with adequate
sized solder pads, and they are soldered both top and bottom with a good fillet
of 60/40 solder, I would be prepared to guarantee that the joints will not
fracture over the lifetime of the product they are mounted in.

If the joint isnt going to get too hot (expand/contract with
temperature causing metal fatigue and cracking of the joint, or
overheat to the point that the solder starts to melt and form a dry
joint), or suffers lots of vibration that puts mechanical stress on
the join, and is done properly, on clean surfaces with enough solder
and the right soldering temperature it won't give any problems.

In consumer electronics pretty much all components, connectors, wires
etc are all held in their PCB's by solder alone. SMD devices are
usually glued down before soldering, but this is more to keep them in
place when they go through wave soldering, (board is turned upside
down during this process) the glue is not necessary to keep them there
once soldered in. (note - wires that go to plugs and headers are
typically crimped or use IDC to hold in place).

What is done in applications like military and space equipment, I dont
know.

I think you are thinking back to the old days with valve equipment
where there was a belief that joints (component leads and connecting
wires were attached to tag strips) should make adequate electrical
connection without needing solder (by being wrapped around the
terminal, or later, wire wrap,) and the solder should only be applied
to cover, protect and seal the join, not to make the electrical
connection.

If you have ever tried to unsolder and remove a component from one of
these chassis, you will know what I'm talking about :)

That's done routinely - see "feedthrough capacitor". :-)

One's that do so for components with external mechanical stresses on them 
and no other mechanical means of support - yes, misguided.

Funny about the millions that have been working just fine for more
than 25 years, and it having the best rep in the industry for physical
reliability. Pardon the pub, but that ain't no fluke.
I've seen a lot more plastic banana jacks break than those Fluke PCB
barrel ones.

There is a degree of mechanical support there too *as long as the original 
Fluke leads are used * - the lead's plug 'rubberised' ('plasticised' ?) hilt 
moulding steadying the plugs in the holes, and transferring downward force 
to the casing rather than the PCB.
