ABSTRACT:
A method is provided for securing a thermoplastic insert between first and second skin sheets of a sandwich panel using an installation tool to rotate the insert about a central axis. One of the installation tool and insert are provided with a male connection feature and the other is provided with a female connection feature such that the installation tool and insert are axially movable toward and away from each other to engage the male and female connection features without requiring relative rotation. The male and female connection features include mating surfaces offset from the central axis to transmit torque between the installation tool and insert. The insert is magnetically attracted to the installation tool by providing one of the installation tool and insert with a magnet and the other with a magnetic material to be attracted by the magnet. The installation tool and insert are then rotated while force is applied in order to drive the insert into the sandwich panel and to frictionally generate heat to friction weld the insert to the sandwich panel.
