As the title says, I have these speaker terminals, also some phono sockets, both with the same 'bizarre' (to me) connection, a small hole and a kind of cut of semi cylinder section at the end... I'm sure there must be a standard way of attaching/soldering these but I'm clueless, so help is appreciated!
Thanks guys

It's a "solder cup."
Insert the end of the wire (with insulation removed) fully into the cup and solder. The solder will fill the cup and surround the wire.

Yes, but mount the posts first, and tighten the nuts with the solder cup on top. Any solder on the threads will make removing the nut in the future doubtful.
Use the semicircle cutout as a target for the iron tip. Allow a moment or two for the heat to dissipate into the metal. Then apply solder at a point as far into the cup, ie as far from the wire insulation, as possible. The insulation should be a millimeter or so from the end of the cup (I'm unable to quote any spec for that).
If you "Tin" the connection point and the wire(s) first, all you need to do is place things where you want them and apply heat. Less chance of applying too much solder and making a mess. The moment you see the solder "flow", remove the heat, hold steady while it cools, and you are assured a good connection..
I usually add the most solder in the cup and lightly tin the wire(s). When the wire pushes into the cup when applying the heat, I know that things are hot enough. The key is to hold things steady at the moment you pull the heat away..
Hope this helps..

Or you could use a solder tag and second nut.
Make the first nut mechanically tight, then add the tag (pre-wired/sleeved?) and second nut.
