  • Patent number: 10731355
    Abstract: A mounting device or bracket for paneled building surfaces is disclosed. The mounting bracket includes an upper wall in the form of a flat surface for supporting various types of attachments. An elongated mounting slot extends through the upper wall, and the mounting bracket includes an elongated nut receptacle that is positioned below this elongated mounting slot. With an attachment being positioned on the upper wall, an attachment fastener may be directed through the attachment, then through the elongated mounting slot, and then may be threadably engaged with a nut that is positioned within and movable along the nut receptacle in its elongated dimension. The elongated configuration of the mounting slot and nut receptacle provides adjustability for the position of the attachment fastener relative to the mounting bracket, including after the mounting bracket has already been installed on the building surface.

  • Patent number: 8523504
    Abstract: A license plate security device comprises a spin barrel into which a license plate mounting machine screw is inserted. These are inserted into a spin barrel assembly with a closed bottom and an open top. The license plate is installed on the vehicle using at least one of these license plate security devices, more machine screws, and an ordinary screwdriver. A machined slug is inserted into the opened end of the spin barrel and secured by security set screw to keep from getting access to the head of the machine screw. With slug in place it helps keep out dirt, water, and rust. Removing the license plate now requires a security tool to remove the security set screw from the spin barrel and slug to access the head of the machine screw. Turning the spin barrel only will not remove the machine screw because it cannot transmit enough torque.

  • Patent number: 8506222
    Abstract: A nut plate assembly includes a nut retainer and a bushing for expanding a tubular body of the retainer. The retainer assembly is used to cold work an opening of a workpiece in order to fix the nut retainer assembly relative to the workpiece. A nut member can be snapped into the retainer. A method of installation includes passing a mandrel through the bushing to radially expand the bushing into a tubular body of the retainer. The tubular body is compressed between the workpiece and bushing as the bushing is displaced radially causing corresponding radial displacement of the tubular body. The expanded bushing applies pressure to the tubular body for a desired fit between the nut retainer and workpiece.

  • Patent number: 8506223
    Abstract: An low-profile cam locking fastener assembly in which a locking nut is connected to a locking washer through a tubular skirt that extends from the nut opening. The skirt and nut opening are coaxial having contiguous inner surfaces that are threaded to receive a bolt or stud. The washer is mounted to the skirt so as to be rotatable with respect to nut as well as axially movable to a position in which cooperating cam elements on opposing faces between the washer and the nut are separated. The cam elements are arranged so that when the nut and washer are fastened down to a bolt or stud on a workpiece, the cam elements engage one another to substantially prevent the nut from loosening from the threaded bolt/stud.

  • Patent number: 8465240
    Abstract: A vibration resistant fastening system including a high fatigue strength bolt made from a first material and a nut made from a second material that is softer than the first material of the bolt. The bolt includes bolt threads and the nut includes pre-tapped nut threads that match with the bolt threads. The fastening system utilizes a combination of unique geometry of the nut and bolt threads and a hardness differential between the nut and bolt to provide vibration resistance. When tightened, crests of the bolt threads embed into the soft bearing flanks of the nut threads. Simultaneously with the bolt crest embedment, the softer nut thread crests flow radially inward into the root radius of the bolt threads. This complete contact between the nut and the bolt restricts the nut from moving in a transverse direction relative to a longitudinal axis of the bolt.
