Most of the concrete posts I've ever used have several holes already and one
simply uses long galvanised bolts and nuts to secure the wood.

Also, is it reinforced by rebar rods inside? Avoiding hitting those is a
very good suggestion. Brian

I'm planning to hang a pair of wooden garden gates between the house
wall
on one side and a concrete fence post on the other. The hinge posts
(i.e.
the wooden post fixed to both the wall and the fence post) will be 70mm
square and approx 1.7m high hardwood. I'm thinking of 4 fixings for
each
post. Any suggestions re the type and size of plugs/screws?

Yes, I understand about the problems drilling into concrete fence
posts.
I don't have an SDS drill but could probably borrow one or hire one if
absolutely necessary.

It's the type and size of fixing that I'm not certain about.

If you drill anywhere near the edge the concrete will shell off.

As I said, I understand the problems with drilling in concrete fence posts.
I can't guarantee what this post is like (my neighbour had it put up a
couple of months ago) but as I understand it the rebar is usually in the
corners where the section is considerably thinner. I'm intending to drill in
the middle of the post, or slightly off centre alternately to give some
resistance to twist. I have seen various clamps but I'm not too keen and
would like something more permanent.
So.... again as I said, what type and size of plugs/screws? Masonry screws?
Frame fixings? Ordinary rawlplug and woodscrew (and if so what
length/diameter)?
