Kind of solved it

So kind of I am understanding how to do it and I made some progress on the rivets on how to do it.

What I did?

• Selected an edge loop which could serve as a path for my rivets, and dupplicated it.
• Then I separated it by pressing the P key.
• Selected the newly seperated edge loop and right clicked on it and:
  • Convert to > Curve
• Created a rivet from a cylinder.
• Selected the curve and set the origin of the curve to it's center.
• Then with Shift + S, with the curve selected, I clicked on cursor to selected to bring the 3D cursor to the origin of the curve.
• Select the rivet, and with Shift + S, choose Origin to Geometry.
• Then with the rivet always slected, again with Shift + S, I clicked on Selection to cursor.

Making the array:

• Selected the rivet and added an array modifier.
• On the array modifier, I set a Factor X to 1.500 to set a distance between the rivets (change it as you like) and increased the number of count to 44 to cover the full distance of the curve. Again, here, you can set a number that fits your case.
• Finally, add a curve modifier and choose the created curve (create the curve with Curve Array - Magiccurve plug-in as Curve Object.
