Mystery holes in wall

[Tim Downie]

Whilst working up a ladder to paint the gable wall of our house (that never normally gets seen much), I realised that there were two small holes in the wall.

Each hole is about 25mm in diameter and in each hole is a threaded brass (looking) inset. The insert has a blind end and is about 30mm deep.

the pics but they were done with a mobile phone up a ladder.

Any suggestions as to what they might be there for? Could they have been left over after some sort of threaded anchor bolt has been used? They don't look like they expand like an anchor bolt. They seem to be a single solid piece of metal.

Tying on a ladder when the last owner painted the gable wall?

To hold a flag? satellite dish?

I'd have thought so... photos showing the relative separation of the holes and their position with respect to the building would probably be more helpful tho.

Maybe once held a bracket for phone / power? (any sign of holes for cable clips further down the wall?)

We've got some like this, and ours were left over from when the builders had scaffolding put up.

The scaffolders obviously needed to tie the scaffolding to the building at some points.

Nope. They're about 10' up and spaced about 15' apart. Some sort of temporary anchor seems likliest but they just don't look like they're any sort of expanding anchor. As I mentioned, they seem to be solid brass and at first sight, look very like the female ferrules on the end of a drain rod set (but with a rather finer thread).

I guess I should just stuff some filler in and paint over them but we've not had a damp problem or anything with them.

Same here. I asked them to leave the eye bolts behind too, as I thought they might be useful attachment points for something.

They sound like drop in anchors. They do expand at the back, but they use a setting tool and you can't really see from the front.

Looks like these:

these: on larger scaffolding jobs, have a look for short stubs of tube (usually vertical) going though the rings on the next one you see.
