Pink large head tri-fold rivet 3/16" Dia Aluminium Body/Aluminium mandrel
Trifold rivets are a style of blind rivets that are specially designed for structural and other high-strength applications. Also called Tribex/Tribulb/Tri tite/bulb tite/Olympic rivets. These rivets have three notches cut into the body of the rivet.
these trifold rivets feature a slotted sheath; 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 rivet body sheath splits to form wide-spread legs to create three “wings” on the blind side of fastened material.These three legs hold tightly onto the installation surface.This provides a more substantial load spread on the bearing surface.This unique design helps Bulbex blind rivets resist pullout or cracking when installed in brittle and/or soft materials such as plastic.
