A closed end rivet, also known as a sealed end rivet or sealed blind rivet, is a type of fastener used to join two or more materials together. It is called a "closed-end" rivet because has a mandrelthe central rod inside the rivet) that does not protrude from the rivet body when the rivet is set. Closed end rivets are commonly used when it is difficult or impossible to access the joint from both sides. They are particularly useful for applications where one side of the joint is not accessible or where a watertight seal is required. The closed end of the rivet prevents the passage of liquids, gases, or contaminants through the rivet hole.
