I don't believe they have a 'modern' name.  They were an odd kind of sheet
metal screw with ACME threads, but ACME threads are nearly obsolete now,
only used in odd places like house jacks and lead screws on thread-cutting
lathes.

In spite of ACME threads normally being stronger, I don't believe this
application calls for much strength.  You should be able to use almost any
sheet metal thread with a similar minor diameter.  However wood screws are
normally tapered, which doesn't work so well in those clip nuts.

Sorry, can't help there.  But the ones from TRF are nicely plated, so I
wouldn't think corrosion would be a problem for at least a decade or two.
