ABSTRACT:
A hem joint for a vehicular closure structure assembled from stamped sheet metal includes an inner panel having circular raised anchor pins formed integrally with the inner panel prior to assembly of the inner panel with an outer panel. A flange formed from the outer panel is coined over each anchor pin so as to completely encapsulate an end portion of each anchor pin, mechanically interlocking the inner and outer panels.
