It would be my wild guess that it was a groove pin. Does it have a groove lengthwise, along one side of it? The grove makes it a hair oversize so it has to be forced into the hole. That holds it in place. But I could be incorrect on the guess. A good hardware store might have groove pins. http://www.mcmaster.com has ’em if you want to buy a package of them. Truth is, most of us old guys probably would use whatever hardened stock we happen to have laying around—like a broken drill shank. And yes, most of us make our own brass shear pins from common brass stock.
