A fastener for a corrugated sheet includes a cylindrical assembly including elongated, plate shaped fastening members assembled as a hollow cylinder. Each fastening member is tapered to one end to form a hook at one end and having a curved groove on an outer surface, and a curved trough on the outer surface at the other end of the fastening member. The curved troughs are assembled to form an annular recess. A retainer ring is secured to the annular recess. A ring-shaped elastic member is secured to the curved groove. A first sealing member is put on the retainer ring. A threaded bolt driven through a washer, the retainer ring, and the fastening member. An expansion nut has a multi-sided outer surface and is moveably secured to the threaded bolt.
