A friend used to (haven't seen him in decades so no idea if he ever "learned better" :>) part the strands into two groups. Then, slip the screw between the groups. Finally, twist the groups together on the "far side" of the screw. I.e., the screw is now captive to the wire.
This made it easy to attach wires in often hard to reach places -- but it was just *so* wrong in so many ways! :< (copper on the "right" side of the screw ends up being pushed out of the way as the screw is tightened)

The 'spring' in what you screw down on is what maintains pressure on the screw threads and so maintains friction to prevent the screw turning.
Compare the 'springiness' of a bit of solder with a similar bit of copper wire and why it is a bad idea is obvious (and the copper will work harden and become even more 'springy').
If you really don't want to use ferrules a dab of solder right on the end will hold the strands together while keeping just copper under the screw but it is hard to achieve consistently.

Is it ok to solder the tips of stranded wire before inserting into a terminal block? I like soldering the tips so that there's no wire fraying or free strands. But...Does the solder slowly compress after awhile and the wire gets loose? Sure I could perhaps a crimp on pin terminals to stick in the terminal block. Ex: http://www.molex.com/pdm_docs/sd/192110001_sd.pdf I'm afraid I'll have to buy a ridiculously priced crimping tool that'll get used a few times and then be forgotten. :(
