Those were explosive rivets, used for repairs back when your trailer was still a baby. You can't buy them anymore. I found a few near a repaired area in my '59.

The hollow backside was filled with a small charge. When you heated the top, the back end blew out and formed a nice upset.

Shari is right on the money here, I haven't seen these since the 70's. The name as I remember them are "self plugging friction lock blind rivets" they are made by both Cherry, and Olympic, and we called then "Oly"s. They are not considered a structural rivet. They install the same as the Olympic rivets used on repair of Airstreams today. The stem breaks off and require shaving. If you could replace them with solids you would be better off.

Those rivets are the old "explosive" type.

They have been history for at least 35 years.

They were the "approved" method of sheet metal repairs, back then.

If you have some explosive rivets that are loose, simply buck them a little, and that fixes the problem.

I had a 58 overlander that had the whole side replaced with those explosive rivets. It was not noticeable from the outside but after removing the interior panels it was obivious that the whole side was replaced. Every one of them were loose and leaking. I wish I had thought of bucking them to tightening them up.

Explosive rivets were installed using a 350 to 500 watt soldering iron, that had a tip that matched the brazier head of the rivet.

You had to apply a little pressure in order for the heat to quickly transfer.

That was the cause of loose fitting rivets, since that pressure cause the metal seams to push inward, especially on segments, unless you were very careful.

They don't look like CherryMax to me. That rivet has a bulb on the bottom of the pull stem that fills in the hole in the back side of the rivet when it's pulled. Also, the pull stem is visible on the head of the rivet where it breaks off. I can't see any evidence of a pull stem on the heads in the photos.

Way back there was an "exploding rivet" that was installed in the hole and then heated with a soldering iron to cause the rivet to expand below the sheet metal. I've never seen these installed, but remember seeing ads for them in the aviation publications back in the 60's.

Wow

I knew my navy training would come in handy someday. Sure has been a long wait. I thought you guys were kidding about explosive rivets.
