ABSTRACT:
A fastener assembly for attaching roofing insulation to roof decks. A washer with a broad load-distributing flange has a crushable region which is deformed as the fastener becomes fully seated. This region insures that the joint is loaded with a predetermined force before the depth-sensitive driver disengages reducing the likelihood of overdriving or underdriving.
