Thanks for the advice, but what's a "floating fastener" Thanks.

Something which holds down but permits movement perpendicular to the hold.
Z-shaped pieces of metal screwed one to top with the other riding in a
groove, pan head screws in grooves, any number of options.

Search on table to fasteners will produce all kinds of info.
