I do not trust glue (alone) for findings for polymer clay.
I took a workshop on glues with a jeweler at a national conference at Arrowmont a few years back, and he said polymer clay is not truly compatible with any glue. The chemistry of the clay interferes with the chemistry of glues, if not immediately then over time. (Chris Heinz?? I forget his name.)
His best suggestion was good two-part epoxy, the five minute kind is ok but the 24 hour kind is better.
I use cyanoacrylate glues a lot, but not for anything that is meant to hold the weight of the whole piece (unless, like a pin back, it is both glued on AND covered in clay that is baked in place.) That is a chemical AND a mechanical bond. They reinforce each other.
I like to embed bails or wire supporting bails into the raw clay, using glue if needed to strengthen the bond, but not as the only component. (Sometimes that means specific findings aren't too good with the clay.)
Some people might have good results long term with glue-on bails for light weight pendants, and you can probably trust their advice. But it's not good enough for me, coming from some college courses in jewelry design using precious metals and soldering.
Your mileage may vary, of course!
