There is a difference when the angle is turned to the edge of the concrete column or to the inside part. When it's turned to the inside part, the basic problem is about embedment lost and of moment forces working on the edge of the wedge anchor rather than a simple tension force.

For a less precise test, in case you fear that the installation procedure was not followed as required, a very...
Wise guys shouldn't forget that most columns are working under pression and have usually much more rebars than standard walls.
The probability of a pry-out failure, for what I learned when I was sent in Hilti university had been reached in tests only in very small anchors in very low depths...
If you have a 4 inch concrete slab, although it's forbidden by the norms, a very efficience way to use them is to use concrete screw that are getting close to the edge. Of course you won't get the whole capacity of the anchors but you will get followinf of our experience very close to it.

Following our own experience with our epoxy anchors, We have connected a dubble cylinder anchor made of 40cm of 60mm diameter and 50cm of 35mm diameter in a drilled hole of 80mm diameter.
For the evaluation, we took the data's relative to a rebar of 36mm in a hole of 40mm although it was far...
