insert bolt on curved surface

[rf.infissi@libero.it]

I have a problem to insert a bolt from the center contained in a hole that crosses a pipe but cannot be inserted since there is no support plan, I must force to bind manually possible do not give us another way?
I tried to create a tangent plane to the face of the tube to use it as a fixed surface of the bolt but nothing to do does not take it as plan

Yes, but you can't make a bolted connection with the generator.
