If the threadsets are as stout as mine, it will take some major mo-jo to crunch the rivet, but that would be the way to go.

I have 2 sizes, 1/4 and 5/16 and the handle is notched for the different sizes, and the 5/16 is shown in the picture. The insert od is 7/16, a little more, about 15/32 in the "split" area. Full crush is right at an inch.

An inch seems like a large hole for a bolt rip-out. A study was conducted and it found that the majority of people do an incredibally lousy job at guestimating an inch, with most people seriously short-changing an inch.

The tool Bob shows is the ticket. Maybe not, but check your measurements on the damage because an inch seems like a lot of hole leftover from a pulled-out bolt.
