ABSTRACT:
A fastener assembly for connecting lightweight roofing structure laminations is shown. The assembly comprises a toggle bolt with an unremovable toggle nut on the lower end of the toggle bolt stem, securing the lower surface of the lamination, and a flanged cap nut threaded on the toggle stem's upper end which secures the lamination's upper surface. The flange cap nut is fitted with a recess complementary to, and adapted to receive a keeper nut fitted with a recess which allows torquing of the flanged cap nut. The keeper nut is also adapted to connect with the top end of the toggle bolt stem in a way, that locks the flanged cap nut and toggle stem together so that the same are incapable of independent rotation, thus preventing the loosening of the fastener assembly.
