ABSTRACT:
A fastening assembly for use in attaching articles to soft materials such as gypsum based and light weight concrete roofing. The assembly includes an anchoring element which has a high thread and an axial bore in one end. The thread has an included angle of less than 45.degree. and terminates in a sharp edge at the free end of the anchoring element. A headed screw is driven into the bore and becomes fixed to the anchoring element. A flange is integrally molded and frangibly connected to the bored end of the anchoring element, and becomes a washer upon breaking away therefrom.
