Spreading Load, Maximizing Strength: Why Tri-Fold Rivets Outperform
In applications involving composites or thick materials, conventional blind rivets often fall short—limited bearing area, risk of pull-through, and unstable fastening are common problems.
Tri-Fold Rivets are engineered to meet these challenges.
Upon installation, their three legs expand behind the joint surface, creating a wide footing that spreads load and reduces stress concentration.
This tri-directional expansion gives a larger internal contact area and significantly boosts pull-out resistance and fastening strength.
Whether fastening heavy metal sheets, reinforced composites, laminated structures, or irregular materials, tri-fold rivets deliver secure, long-lasting connections with one-side installation (no need for back-side access). Choosing tri-fold rivets means adding a stronger, more enduring layer of structural assurance.
