ABSTRACT:
An installation tool, fastener, and method for installing the fastener are disclosed. The installation tool has control fingers which control the position of the fastener with respect to the plunger and workpiece to which the fastener is to be attached during the entire travel of the fastener from the entry into the installation tool to installation in the workpiece. The fingers are pivotally mounted to the plunger and travel with the plunger throughout the installation path. The fingers are adapted to engage the fastener in a displaced area on the fastener so that the fingers can control the fastener through installation of the fastener into the workpiece. The displaced area is positioned between the top and bottom of the fastener so that the fingers can maintain control throughout installation.
