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?

what's going to be the side pressure on these? they have expanding bolts
that you drill holes, insert bolts, and wrench them to get them to expand.

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.

Accurately measure the size of the holes on the flange then go to Lowes or
Home Depot and ask them to show you the "RedHead" fasteners
http://smithfast.com/redibolt.htm I'm guessing you'll use the 1/4" ones

Make sure you get the proper sized drill bit.. It probably wont be a 9/16"

If there s a Harbor Freight Tools store where you are, get a whole set of
masonry bits for a few bucks. They dont last forever but are fine for "odd
jobs" like you re doing

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.
