Tips for removing heavy duty fixing

bbat

Asking for more tips! The previous owner had a TV attached to the wall. Two of the heavy duty fixings have been left (see photo) Any tips on getting them out? I've tried youtube but maybe I'm searching for the wrong thing as I can't find anything. 
Thanks

Use a similarly-sized bolt or 'drift' to tap them in below wall surface level, and then just skim over them. Jobbie jobbed.

The bottom one's slotted and looks like the type that can just be unscrewed. For the top one, just as @Bendy_House said. Only thing I'd add is before skimming over them, paint over with a dab of primer as gypsum plaster/polyfilla can rust steel very rapidly while its going off, leading to staining that will show through the paint.

OK thanks both! I've tried to twist the bottom one but no luck. I'll try tapping both in a bit tomorrow. Thank you

Before you start filling the holes, use a scraper or similar to remove the flaking and/or raised surfaces.  In effect, try to 'countersink' the hole all around.

And yes, tap the fixings in, rather than attempt to pull them out.

I was told to do this:
What you see are the collets of the expanding section of the "rawl plug"
Try putting the bolts back in - only part way, and knock the bolts sideways/up/down until the ring holding the collets splits and the collets and wedge "fall" out.

Worked for the bolts left to me.

Hitting anything which is fixed in a wall sideways/up/down risks cracking or otherwise damaging the surface finishes - they aren't designed to be loaded in this way.  It might work, but at the risk of doing damage which will be time consuming to repair.  There's nothing to be gained by attempting an extraction (unless the OP needs to reuse the holes immediately).

Holes need to be filled anyway, I normally just hit it with hammer- 1  fast hit to push it about half an inch in to the wall, dollop of filler over, job done. Less time and less playing  about compared to trying to take it out, and once filler dries, as good as any other way.

Grenage

Anchor bolts never come out without destroying the wall around the fixing.  I'd also just spot prime (or use any oil-based paint) and fill.

The two visible plastic fixings look like simple rawlplugs to me and you can often get these back out, either by half-screwing in a suitable screw (as mentioned above) or by pulling with fine-nosed pliers.

When trying to get them out, I like to screw in a screw which is a bit too small for the plug (e.g. these 10mm grey plugs, part screw in a 4mm or 5mm screw)

The screw is big enough to bite on the plug, but small enough to not expand the plug and jam it into the hole. With it screwed in a few turns, whip it out with a claw hammer. 

That said, as per the first reply, if getting them out doesn't turn out to be easy, tap them in further and just skim/fill them over.
