"I wonder about the adhesives they use on these granite counter tops, drill it first and a stainless steel pin?"

They have a special glue and fill in with mortar. That glue is amazingly strong.
Think 3 or four small steel pins would stop it from twisting over time.
Tile place will have the glue and anything else you need.
Seems like this would be a bit under $40"
