Remove shorn bolts from concrete?

Previous homeowner had a gate here that he removed at some point and cut off the bolts at the ground. We want to replace the gate, but I'd rather use these holes since they also line up with holes in the wall.

Any chance I can get these bolt removed? I have some screw extractor bits but they don't seem to make any progress into the metal bolts.

You'd have to know exactly what style those are to remove them.
They are more than likely some type of expansion bolt and will not be coming out.
Extremely doubtful you could drill them out.

Thanks...that's kind of what I was thinking. So the next question....if I was going to just drill new holes and put in new bolts, what is the best kind to use in this situation?

There are several different types. The one in the link is easy to use and strong.
Red Head masonry fasteners

For a gate I doubt they would be expansion, or red head style bolts.

Give one a try, drill it out, buy an easy-out and see what happens!

There is no visible shield.... nothing to pull the bolt out of.

I'd use expansion bolts and I'd doubt any of them could be drilled out and they certainly can't be pulled out.

They look to me to be like PJMax suggested. If so, you won't be able to pull them, but if the hole was drilled all the way through to the concrete you might be able to drive them down into the soil. Don't beat on them too hard because if they're not all the way through you could break off a decent piece of concrete on the bottom side of the pour, but take use a hammer and drift to see if you're lucky enough for them to go down.
