For the plywood attached to the concrete.
2 1/2" long stainless steel lag bolts with stainless steel washers
plywood was counter sunk 1/4"
lag bolts went through the plywood and screwed into the concrete floor which had threaded inserts sunken in by drilling holes with a hammer drill 2" deep. When the lag bolts are torqued down they expand the inserts against the wall of the holes in the concrete.
For the Oak attached to the plywood.
Counter drilled 1/4"
used Torx head fasteners for decking because of the resistance to stripping out.
Plugged the holes using Oak dowels with a little dab of glue on them, tapped them in with a hammer and cut flush with a special saw. (can't remember the name of it)
I wanted everything done so it could be easily repaired if nessessary. The Torx fasteners will come out easily as well as the lags if I really need to dig in deep. I made sure to use plenty of vapor block (6 mil poly sheeting over lapped and a 3-in-1 vapor barrier/padding/ insulation.
Even when it was -20 degrees F outside, the floor was as warm as the room. You could walk in bare feet without discomfort. I thought the floor would of felt colder than it did. I am glad I was wrong.
