A fastener/plate assembly for fastening material to a roof deck employs a threaded fastener having a shank with two thread sections. The distal end portion of the shank has a thread which is loosely insertable through an opening of the plate. A second thread of the shank has a thread diameter greater than the first section and is threadably engageable with the plate. The driver end of the fastener is dimensioned so that during an overdrive condition, the fastener may threadably disengage from the plate to allow the driver end to pass through the stress plate opening.
