I call it a "D" nut, in Brattons catalog they are called clinch nuts. They are on page 164 of the 2018 catalog under special hardware.

I’ve never installed any, but I understand you’ll need some sort of special tool to install them.

Back up the D-nut with a bucking bar, Then with a ball peen hammer peen it over. All you want the D-nut to do is not turn or fall out. That's if you have room to swing the hammer, if not use a C clamp with a large ball bearing and again hopefully you can reach with hole. If these don't work, if you get steel D-nuts you could tack weld them. All else fails JB weld.

I fixed these nuts with contact adhesive before assembled.

I never used weld or adhesive. Just pulled them into place with a screw and fender washer. They're snug enough they don't go anywhere.

Drill a round hole and use a small square file to create the four square corners .

Broaching is the process of manufacturing precision odd shaped holes including square and rectangular ones. The "D" holes in sheet metal are punched.

My father was an excellent toolmaker and engineer/machinist. At one time, he worked for a company that amongst many other things, used to draw wire. the process was to pull a thicker piece of wire through a die with a slightly smaller hole in it. The wire stretched as it came through the die and you ended up with a smaller diameter wire. The dies obviously had to be very hard to last long. They used carbide. Now, the challenge! Try drilling even a round hole in that, then try making a square or rectangular hole in it, then polish it. He did many. (Imagine making the hole then polishing it for the finest strand of wire you have ever seen. They went down to less than 0.001")
I was intrigued, even as a kid to see him do it. It was a slow process. A mask was made of an insulating material with an appropriate hole in it. The mask was clamped to the surface of the block of carbide and a moving electrode set in motion in the hole. It would wander randomly around within the hole in the mask, making sparks as it went. Gradually the carbide was eroded till the hole went right through. Then came the arduous task of polishing the inside of the hole. Electric Discharge Erosion is not new but sometimes, even now is the only way. A friend once broke off a tap in a hole. EDE was the only way to save the component. (with a of of patience)
A square hole in mild sheetmetal? NO PROBLEM.

Broaching we do for key ways and heavy materials,In model making we used a number of different technique. Now mind you this was years ago before fancy expensive technology. A chassie punch came in many shapes as well as adel tool for cutting small squares or key ways in sheet metal .

I use a hack saw to cut a few notches in the raised lip of the nut then I can pinch the lip over with vice grips or bendit over with a hammer.
