ABSTRACT:
A plastic-headed fastener assembly has a first outer and a second inner sealing flange. The second flange performs the secondary function of engaging the upper panel of two a member assembly which tends to climb the threads and holding it away from the head. The threads on the fastener can then strip out the hole in this upper panel so that it may return to its position adjacent the second member. This flange prevents damage to the plastic head which can result from friction generated heat.
