Tri-Bulb Rivets expand in three directions as the mandrel is pulled through them, creating three anchor points on the blind end of the application. They have better retention than a standard pop rivet due to their increased surface area. These rivets also work better in thinner metals without causing damage to the materials. Aluminum Tri-Fold Rivets are used for their high strength to weight ratio, and corrosion resistance.

Recessed Crown Dome Head Tri-Fold Aluminum Rivets create a finished look similar to a standard pop rivet, and do not require any special tools for installation (other than a standard riveter).
