  • Patent number: 11754109
    Abstract: A polymeric fastener for use in the construction industry for fastening wood and other basic materials together. The polymeric fastener can be formed in the basic shape of a nail and/or a staple-like fastener. Preferred embodiments of the polymeric fastener include a hardened binder embedded with a filler and/or a core for adequate strength as required for use with a delivery device powered by pneumatics, hydraulics, or other mechanical systems.

  • Patent number: 11753814
    Abstract: An anchor bolt fastener assembly with specialized connection capabilities and features for attaching building components to concrete slabs, walls, ceilings, and/or structural surfaces. Compression force can be established and maintained over time using a compression washer in combination with a specialized fastener stud that is designed to exploit the compression washer benefits. Methods of using exemplary embodiments include installing the anchor bolt fastener assembly relatively flush with the surface of the concrete slurry by direct insertion in the slurry using a specialized threaded anchor bolt float. Once the slurry hardens, the anchor bolt and anchor bolt float embedded in the concrete slurry cooperate with the specialized fastener stud to secure the building component to the concrete.

  • Publication number: 20210355984
    Abstract: A self-sealing fastener for reducing leaks between the self-sealing fastener and a substrate. The self-sealing fastener includes a shank that extends longitudinally between a first end and a second end. The shank has an outer surface. The self-sealing fastener also includes a head that extends radially outwardly from the first end of the shank. The head has an underside surface that is adjacent to the first end of the shank and a topside surface opposite the underside surface. A mastic sealant is disposed on at least one of the outer surface of the shank and the underside surface of the head to provide a water-tight seal between the self-sealing fastener and the substrate after the self-sealing fastener is installed in the substrate.

  • Publication number: 20200003245
    Abstract: An improved fastener for securing a first building component to a second building component is provided. The fastener includes a head, a shank, and a tip. The shank is connected to the head and extends along a longitudinal axis to the tip. The shank includes an upper shank portion, a lower shank portion, and a transition zone. The upper shank portion is located adjacent to the head. The lower shank portion is spaced from the upper shank portion and is located adjacent to the tip. The transition zone is positioned longitudinally between the upper shank portion and the lower shank portion. The transition zone is longitudinally spaced from the head by a pre-determined distance. The pre-determined distance is associated with a thickness of the first building component such that the transition zone is aligned with a joint between the first and second building components.
