GESIPA Tri-fold rivets form three folded legs that distribute the fastener's clamp-load over a larger blind side head formation. The larger blind side head prevents cracking of brittle materials and greater pull-through resistance in soft and ductile material applications.

Note:Above values are to be used as a guide and may vary depending upon the application. Shear and tensile strength tests were conducted in hardened alloy steel
sheets at nominal grip. Rivets 64, 65, 66 use special Tri-fold pin. Rivets above 66 use standard Bulb-tite pin.
Tri-fold rivets are used in automotive applications such as plastic body panels, trim, and interior components.
