Specialty Blind Rivets

Tri-Fold

Tri-fold blind rivets mechanically deploy into three distinct, wide legs on the blind side during installation, maximizing the bearing area and mitigating pull-through risks. This gentle, distributed clamping force ensures structural integrity without fracturing or deforming brittle, thin, or soft substrates. Featuring wide multi-grip capabilities and often incorporating a locked mandrel core for rattle prevention, they offer versatile, vibration-resistant performance. They are heavily specified for composite material fabrication, automotive plastic body panels, and RV structural repairs where dissimilar or delicate materials must be permanently joined.
