Duplicate with transform is just the ticket for you
Select the first rivet, then open the Duplicate option box, turn transform on. You may have to change to Parent from World to get the box useable. Now hit duplicate. Move the second rivet where you want it, keeping in mind that each rivet you make will be spaced the same way from the next one in line. Then once you have it moved, hit ctrl+d and keep adding rivets
Red bellows of flame have blackened my stones
Convulsing my frame and cracking my bones
Hell's dragons of steel who roar in their chains
Crawl into my caves to suck out my veins.....
