An elongated strip of adhesively attached preassembled lock washers and nut assemblies for attachment to threaded shanks of bolts for joining members together, the strip having a strip face provided with a peelable type adhesive, a series of lock nuts each having a star washer in unitary assembly therewith, an adhesive ring with opposite faces each provided with a peelable type adhesive material with one face being retainingly secured by the adhesive to said lock nut and with the other and opposite face being secured by the peelable adhesive to the peelable type adhesive on said strip, the lock nuts being adhesively secured in spaced relation to the strip along the length thereof in readiness for each lock nut to be peeled free of the strip for attachment to a member by the adhesive material for assembly therewith.
In combination, a pre-assembled lock washer and nut assembly, at least one metal plate to be secured with said assembly, the assembly including a nut, a star washer integrally fastened to the nut by a screw thread from the nut, and an adhesive ring provided with adhesive on axially opposite faces of the adhesive ring, the adhesive on one face joining the ring to said washer, the adhesive on an opposite face of the adhesive ring joining the nut to said at least one plate, said bolt and nut being operable for drawing the nut and for drawing the washer in embedded assembly with a confronting face of the metal plate so that biting edges on the star washer can actively bite into said confronting face of the metal plate to further resist rotative action of the adhesive lock nut as the bolt is screwed tightly into the nut.
In combination, a pre-assembled lock washer and nut assembly, a pair of metal plates to be secured together by said assembly, the assembly including a nut having an internal thread, a bolt with an external threaded portion threadingly engaged with the internal nut threads, a star washer fastened to the bolt by the external thread portion of the bolt, and an adhesive ring provided with an acrylic adhesive on axially opposite faces of the adhesive ring, the adhesive on one face joining the ring to said washer, the adhesive on an opposite face of the adhesive ring joining the nut to one of said plates in closest adjacency to said adhesive ring, said bolt and nut being operable for drawing the nut and for drawing the star washer in embedded assembly with a confronting face of the metal plate in closest adjacency so that biting edges on the star washer can actively bite through the adhesive ring into said confronting face of the metal plate to further resist rotative action of the nut as the bolt is screwed tightly into the nut.
