Not sure if this is a question related to assembly mates or sheemetal modeling.  I am trying to assemble a fastener to a curved sheetmetal part.  The issue that I am having is that I am unable to find a mate that will insert the bolt into the hole.  Just selecting the surfaces results in a tangent mate, which does not align the bolt with the hole.  If I preselect a Concentric or Coicident mate, Solidworks returns the comment; Selected entity is not valid for current mate type.

Because it is a sheetmetal feature, the hole is not a true cylinder, I am assumming that this is why these constrains do not work.  I have tried, but am not able to locate an axis that follows the hole though the fold feature.

So the question is, how do I assemble this part?
