Abstract
A method of installing a thermoplastic fastener insert unit into a thermoplastic composite resin panel includes the steps of cutting a hole in the plastic resin panel of a diameter less than the annular flange of the fastener insert unit. The fastener insert unit is then rotated to frictionally generate heat between the annular flange and the plastic resin panel until sufficient heat has been generated to enable the welding of a fastener insert unit directly to the plastic resin panel. Additionally, the lower surface of the fastener insert unit can also be frictionally welded to an interior surface of the plastic resin panel.
