How Do Structural Blind Rivets Work?

Structural blind rivets work slightly different from the typical blind rivet. A structural blind rivet has a built-in (internal) locking mechanism that is designed to hold the mandrel inside of the rivet body after the exposed portion snaps. This is commonly referred to as an interlocking style rivet. Notice how in the diagram below, the portion of the mandrel to the left of the body is also much larger in a structural rivet than in a standard blind rivet.

There are several reasons structural blind rivets keep the mandrel locked inside the body once installed:

  • Increased Shear Strength
  • Increased Pullout Strength
  • Higher Resistance To Vibrations

Benefits of High Strength Structural Blind Rivets

During installation, the mandrel remains within the shear plane of the fastener, yielding high strength under shear loads. In addition, the internal lock ensures positive mandrel retention, resulting in high strength under pullout loads. These rivets provide excellent clamp-up force and the mandrels break flush with the heads when installed. They offer a vibration-resistant connection and are suitable for a wide variety of applications.

Internal locking fasteners have wide grip ranges, and might be used for a variety of applications in order to reduce the number of different fasteners kept in stock.

Choosing The Right Tool Is Important

Most operators of structural blind rivets would agree that the use of the correct setting tool is crucial for a strong fastened joint. Among the main variables to be decided when selecting a riveting tool include power to weight ratio, traction power rating, stroke length, ergonomics, and ability to adapt different nose assemblies to accommodate a wide variety of structural blind rivets.
