Steel 3/16 pop rivet would probably hold it. I have hung a lot of weight on them. Just a bitch to set with a hand riveter.
That would be an excuse to go buy an air driven one, except it wouldn't get used very often so be hard to justify. Not sure I have any rivets that large, have to take a look, then maybe go visit Jeff at his Home Depot. Not his dept. but still a chance to bug him for awhile.

Just checked....HD and Lowes are extremely pricey, as is Northern Tool. However, Harbor Freight has one for $39.99 which would be withing reach, or their 17" long handled unit for $20. Going to take a look at the hydraulic/air unit, sure would make things easier and I'm an advocate for "easy."
