ABSTRACT:
A fastener assembly for use in attaching cover panels to support members in a prefabricated building system where the cover panels and support members have a prescribed total thickness at the point of attachment including a self-drilling and self-tapping screw where the self-tapping thread on the screw terminates a prescribed distance from the head of the screw which is substantially equal to the total thickness of the support member and cover panels so that the screw will self-drill and self-tap its way through the support member and the cover panels and the self-tapping thread will release the support member nd the cover panels when the head on the screw is seated against the support member so that the screw is free to rotate with respect to the support member and cover panel; and a locking member adapted to be threadedly engaged by the screw behind the cover panels to clamp the cover panels onto the support member between the locking member and the head of the screw.
