What is a Tri-Folding Rivet?

Tri-Folding Rivets come equipped with features that enhance performance in areas of odd-shaped applications. They have a long grip range that can handle a wide variation of material thickness. What really sets them apart is that once a Tri-Folding Rivet is set, it folds into three separate legs, forming a wide load-bearing area on the blindside of the material. There are a variety of different head styles, the most common ones being dome head and shaveable head. Our Tri-Folding Rivets (TRE-GO) are made of Aluminum/Aluminum and have a unique mandrel locking feature that requires a special nose piece.

What are the advantages of using Tri-Folding Rivets?

The three separate legs allow for a high clamp-force when working with thin and brittle material. Also, when working with oversized or uneven holes, Tri-Folding Rivets offer the advantage of large leg formations to resist pull through. The EPDM washer creates an additional seal around the perimeter of the rivet head which prevents moisture from intruding.

Additionally, the retained mandrel core adds strength, making the Tri-Folding Rivets less prone to failure under high shear loads. The long grip range can result in reduced inventory requirements and simplify fastener selection.

Areas of application: General construction, automotive, roofing and many more. Tri-Folding Rivets excel in areas of odd-shaped applications such as pipes, corrugations, etc.
