BLIND RIVET 3/16 X 5/8

Blind rivet, also known as a pop rivet, is a mechanical fastener used to join two materials when only one side of the assembly is accessible. It consists of a hollow rivet body and a mandrel (or stem). When a rivet gunpulls the mandrel, it deforms the blind side of the rivet body, creating a secure, permanent joint before the mandrel breaks off.
