Trifold rivets are a style of blind rivets that are specially designed for structural and other high-strength applications. Also called Tribex rivets, these tri fold rivets feature a slotted sheath; when installed, the sheath splits to create three “wings” that provide a large bearing surface. This unique design helps Tri-fold Rivet resist pullout or cracking when installed in brittle and/or soft materials such as plastic.

Tri-fold 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. As the mandrel is pulled in towards the hat, the three sections bend forming three legs. These three legs hold tightly onto the installation surface. Tri-fold rivets break off at the head much like a typical pop rivet will.
