BENEFITS

Sealed Rivet Body: Prevents the passage of vapor or liquid through the body of the set rivet.
100% Mandrel Retention: Because the body of the rivet is closed, the mandrel head cannot fall out through the backside into the workpiece.
Blind Installation: Access is required from only one side.
