Abstract
A fastener assembly for securing layers of roofing material to a deck includes a nut for insertion in and engagement with a pre-drilled hole in the deck and a threaded bolt for engagement with the nut. The nut is provided with resilient legs that are disposed both above and below the hole and that deflect outwardly upon being engaged by the bolt to prevent removal of the nut from the hole. The shank of the bolt is provided with a groove that engages edge portions on the nut legs to prevent counter rotation of the bolt.
