Agreed, in something like a broken leg. Screws are, however, very good 
at pulling otherwise unclampable joints together. After the glue dries, 
you can replace the screws with dowels - or not.

Sheetrock screws are quite handy in all sorts of applications including 
pianos.

Then you need to learn how to use and install them. The hardness of the 
screws is what makes them much more difficult to break then the typical 
low grade imported junk that is sold for wood screws these days. I 
wouldn't be without them.

Not a reasonably recent piano.

Including epoxy, nor will any glue at all bond with the more modern 
glues when the joint fails, whatever you do.
