3/16" (#6) Dome Head Tri Bulb Rivets with Sealing Washer Aluminum

Aluminum Tri-Fold Dome Head Pop Rivets with Sealing Washer

3/16" (#6) Blind Rivet Diameter with EPDM Neoprene Washer

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.

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).
