A web truss and a chord truss are joined or connected to each other. Each truss has an extruded hole with flanges, collars and combinations of flanges and collars. When a tool placed against the flanges they are expanded to form Z configurations. When the tool is placed against a collar the collar folds over another member's bottom portion or, depending on the configuration, another member's collar. These configurations and the folding of collars act to inhibit separation of the trusses from each other. The method and assembly are ideally suited for automated processes in a Just In Time fashion.
