I want to attach a 3in x 3in fence post to the end of a brick wall. The problem is that the wall is only 9in (22cm) from the house wall. I asked a related question (without mentioning the short space) here and "resin fixing" was suggested. I'm not sure if this is intended to attach a post or similar object directly to the brick, or if it is intended to be used in conjunction with bolts of some kind?
I looked in my local hardware store, but didn't see anything appropriate.
Yup, used with threaded rod usually. You drill a hole, pump with goo, and stuff the studding into the hole. Once its gone off, you then have rock solid studs sticking out the wall ready for posts, washers, nuts etc.

Just to add ........... you buy the threaded bar in lengths and cut to size required ...... put the nut on first before you cut the bar, to allow the nut to cut the thread where you have sawn ... otherwise it can be difficult to get the nut on.
Usually with studs rather than bolts. You glue the stud in place, leave it to set and then bolt up later. Rock climbers have "interesting" opinions on the virtues of these.
Fischer are probably the best known maker of this stuff (I imagine their website is informative). You can get them from most big hardware suppliers, inc. the inevitable Screwfix.
You need some studs:

And some polyester resin as either a big tube

individual servings

's a lot of economics to think about here, cost of using expensive single shots vs. the high initial and lower individual costs of the big tubes.
These are worth using, if you're doing a bunch of holes in crumblium, as they can save a good price of resin

't make your own studs from studding unless:
It's M12 or bigger
It's cut with a decent thread, not the usual badly rolled V-crested rubbish
You degrease it with acetone before use.
The thread profile for a resin fixing is _not_ your standard fastener thread. In particular, trapped air on that thread will lead to a very weak fixing.
I'm not sure what you mean WRT the relevance of how far the wall is from the house, unless, as suggested by someone else, that you can't drill into it because of the small gap? - if this is the case, no amount of 'glue' will keep it in place, regardless of whatever it is you use. If you can drill it, you need some ragbolts, these are like coach bolts but the end is tungsten or some other very hard material. You simply drill a
10mm hole through wood and brick and then knock the bolts through lightly, when they reach the brickwork you tighten them with a socket and they cut a thread into the brickwork - they're used all the time to attach wallplates, which hold up entire rooves
If there is insufficient space to get your drill in you could buy (expensive) or hire an angle drill (try Google images). You might also consider an angle attachment for your normal drill but it would be hard work - probably no hammer action. You might find the whole job easier to do using some kind of metal plates bridging both post and brick.
As far as fixings are concerned, I doubt if you need anything as specialised as resin fixings since there are plenty of more basic fixings, such as 'Multi Monti'. Have at look at
Place the post over the studs before the resin goes fully off to make sure everything lines up. More important when 3 or more fixings are used (wall plates etc).
Consider counter-boring the post to accept the heads of the nuts and cut the stud flush. Useful for general neatness or if a gate or fence panel is to be mounted directly on the fixing face.
Don't use glass resin capsules, get the hole too deep or oversize and there won't be enough resin to do a proper job.
Depends on how long you studding is to start with! I quite often get it in 300mm lengths, and hence in this application would cut them in the middle and use half at a time.
