I have two pieces of sheet material that I want to fix together, one is reinforced cardboard and the other is a flat piece of metal that's part of a clasp. I'm looking for a fixing that would function a bit like a pop rivet.
I was imagining something a bit like a nut and bolt with a very short screw thread, but I've had a look in my local hardware stores and I couldn't see anything like this.
Does anyone know the name of a fixing that would function like this so I can search it online to buy some? I could buy a longer bolt and saw some of the thread off, but I thought there should be a fixing for this that I don't have to modify before using.
