I want to insert pin into the bolt. For that coincident mate is the most appropriate one but it is not the highlighted one. How to fix it? Parts folder is attached.
open pin and create axis between front and top plane.
Now mate axis to hole in bolt.
and finally locate right plane of pin to top plane of bolt with a 10mm distance mate.
It looks like the issue that you are having is that Solidworks is not recognizing one of the features that you are selecting as round. If that is the case, then only either re-creating the feature into a round feature or using the solution given by Jim Steinmeyer above will work.
This is a YouTube video. Video is using parallel & tangent mate.
