Abstract of the Disclosure Methods and fasteners are provided for joining thermoplastic articles and for connecting a single thermoplastic article to a non-thermoplastic substrate. A first thermoplastic article and a second thermoplastic article can be placed against each other, and then localized adjacent portions of the articles are heated preferably with an ultrasonic heating device. A sharpened end of a thermoplastic fastener is driven through the heated areas of the first thermoplastic article and the second thermoplastic article. Upon cooling of the heated areas of the first ther- moplastic article and the second thermoplastic article, those articles are locked to the thermoplastic fastener by fusion of the contacting surfaces of the articles and fastener.
