Tri-fold rivets expand in three directions as the mandrel is pulled through them, creating three anchor points. A tri fold rivet has better retention than a standard pop rivet
due to their increased surface area on the blind end of the installation. An expanding rivet works better in thinner metals without causing damage to the materials.
