I need to attach a 2x2 gatepost, with a flange at the bottom, to my
4" concrete sidewalk.

What is the best way of bolting the flange (4 holes) to the
concrete? I have a 1/2" hammer drill with a 9/16" concrete drill bit.

How do I proceed from here? Can I just drill 4 holes in the
concrete with my 9/16 bit and then insert some kind of a fastener in
the holes? What kind?

Do a Google search for "Concrete Sleeve Anchor". I've always had good
luck with them. Careful not to overtighten, however. You can snap
them with a breaker bar.

and be careful how close to the edge of the concrete you place the holes.If
you are right at the edge,when the sleeve expands it can break the side of
the concrete off.
