A fastening assembly for securing objects to a masonry body, such as shutter assemblies used to secure building windows, that includes a screw member, an anchorage assembly, an insert assembly partially housed within the anchorage assembly and a bushing ring coaxially journaling the screw member adjacent to the head. Thick grease is packed with the bushing ring to seal the internal components from the elements. The bushing ring has an internal through opening with two internal diameters. One of them, adjacent to the screw head being slightly larger than the shank of the screw in order to seal the rest of the components from the elements. The other end of the internal through opening being larger so that a portion of the insert member can penetrate therein when the assembly is tightened.
