How Blind Rivets WorkThe standard blind break-mandrel rivet consists of two components, a rivet body and mandrel. The rivet is first placed into an installation tool and is then inserted into the application. Activating the tool pulls the rivet's mandrel, drawing the mandrel head into the blind-end of the rivet body. This action forms an upset head on the rivet body and securely clamps the application materials together. Finally, the mandrel reaches its predetermined break-load, with the spent portion of the mandrel breaking away and being removed from the set rivet. Fast, easy-to use blind rivets offer speed of assembly, consistent mechanical performance and excellent installed appearance, making blind riveting a reliable and economical assembly method.
