A BLIND RIVET CONSISTS OF TWO PARTS:THE RIVET BODY AND ,WITHIN IT, THE SETTING MANDREL. 

• THE BLIND RIVET BODY IS INSERTED IN A HOLE IN THE MATERIALS TO BE JOINED.
• THE BLIND RIVET TOOL IS PLACED OVER THE MANDREL, THE TOOL IS ACTUATED AND THE JAWS OF THE TOOL GRIP THE MANDREL.
• THE JAWS RETRACT, EXTRACTING THE MANDREL WHICH PULLS THE MANDREL HEAD INTO THE RIVET BODY SETTING THE RIVET. AT A PREDETERMINED TENSILE LOAD, THE MANDREL BREAKS FROM ITS HEAD AND IS DISARDED.
• THIS FORMS A STRONG, TIGHT, RELIABLE JOINT. BECAUSE THIS IS ALL DONE FROM ONE SIDE THESE ARE CALLED BLIND RIVETS.
