The pillar-drill thread finally prompted me to get some T-nuts (the sort
that slide in a slot, not the spiky ones) so I can fix my little
vice/clamp properly to the pillar-drill's table.

I was surprised to find the nuts weren't tapped all the way through. The
supplier said they are all like that, so the bolts have to be exactly the
right length. Is that true? It means the bolts have to be pretty-much
exactly the right length.

Well they can't stick out the bottom anyway as they would hit the base of
the T slot.

However I think you want T bolts.
usually they are shaped like a T and you can push them through the top of
the T slot, rotate them about a quarter turn and they stay there while you
put the job and a nut on.
