What am I doing wrong? I bought a glass sink at a bankruptcy auction, but the included expanders to hold the brackets seem too short. The brackets are so thick that the screw can't be fitted. The sink only comes with instructions on how the parts should be assembled, no other tips. The expanders don't have a flange to prevent them from sinking too far into the hole. Is it then important that the hole is drilled to the millimeter with the right depth? I've tried to pull out the expander a bit by turning the nut, hoping it would catch so that I have enough millimeters of screw to put on the nut, but it's not working, it goes back into the wall. Yet I can't get it out of the hole again. What should I do?
It is more like this construction. http://i00.i.aliimg.com/img/pb/469/184/393/393184469_362.jpg
(Correction: The holes are APPROXIMATELY as deep as the expander. They are probably a few millimeters too deep, and this is likely causing my problem)

No, these types of anchors usually only have a minimum depth you need to drill. They secure themselves by tightening the nut until they start to back out of the hole and the flanges catch on the concrete. It might be that the hole is slightly too large, so if you can remove the anchor, you can bend the flanges out a little before reinserting it. But what you can first try is tightening the nut all the way and seeing if the anchor catches.
It worked. "Haka fast" was the word, now it did. The problem was that because I didn't place the drill holes exactly right, and because the holes in the bracket weren't elongated, I previously had to push a little on the expanders to get the bracket in place, which caused them to go back into the wall. But now they had hooked on, so it worked! Thank you once again for the help!
