pop rivet
Today it means: A blind rivet; a rivet which can be fixed with access only to the factory head end; after passing the bucktail through the items to be secured, the rivet gun is attached to a frangible mandrel through the centre of the rivet, which upsets the bucktail to form the field head and breaks off when the correct pressure has been achieved.
