Aluminum Tri Fold Blind Rivets

Tri Bulb Rivets are a special kind of rivet. They are often referred to as exploding rivets due to the way they expand, and also tri tite, bulb tite, and olympic rivets. These rivets have three notches cut into the body of the rivet. They are installed much like a pop rivet, using a riveter to pull the mandrel towards the hat.
