  • Patent number: 10871181
    Abstract: In a method for producing a connecting element, in particular a bolt, a zinc anti-friction coating is applied to a blank made of a metallic base material. Subsequently, the coated blank is deformed in a deformation process to a desired final geometry of the bolt. The deformation process may, in particular, be a thread rolling process. The anti-friction coating is applied in particular by way of a zinc diffusion method. The bolt is in particular an engine bolt, specifically a connecting rod bolt. A bolt of this type has a durability as conventional bolts, but at the same time can be mounted repeatedly by virtue of the formation of the special anti-friction coating without the coefficients of friction increasing above permissible limits.

  • Patent number: 10465077
    Abstract: A method to prevent corrosion of a susceptible article of a two-article system, in which first and second articles of the two-article system have surfaces facing one another and in which the two articles have different anodic indices includes applying a coating material to the surface of the first article and curing the coating material on the surface of the first article. The method further includes contacting and securing the surface of the first article with the surface of the second article. The two articles exhibit substantially no corrosion following exposure to a corrosive environment under standard GMW17026 for a 15 year simulated test.

    Abstract: A screw with double notches includes a head portion, a shank portion extended outward from the head portion, a threaded section spirally surrounded on the shank portion. Wherein, a raw section on the shank portion is provided with a cambered surface formed integral with the shank portion in cross-section, and a notched section relative to the raw section has two cutting notches separately depressed into the shank portion and disposed near an end of the shank portion, thereby forming a protrudent part between the two cutting notches. By means of the cooperation of the cutting notches and the raw section, the cutting capability and the removal of debris are increased so that a fastened object is prevented from split. Thereby, the drilling speed is promoted, and the effort to rotate the screw is lessened. While the supporting strength of the screw is improved, the screw does not break easily while screwing.

  • Patent number: 8506224
    Abstract: A fastener including a bolt and a grommet assembly attached to the bolt for fastening to a work piece. The grommet assembly includes an upper grommet, a lower grommet attached to the upper grommet, a retainer ring, and a housing that houses the retainer ring within the lower grommet. The upper grommet is inserted into a hole at one side of the work piece and the lower grommet is attached to the upper grommet through the hole at an opposite side of the work piece. The retainer ring is inserted into the lower grommet and encapsulated by the housing. The bolt is inserted into the grommet assembly, and the retainer ring engages the bolt such that a plurality of pressure pads extending from a plurality of corresponding spring beam elements of the retainer ring reside in an annular groove of the bolt. The grommet assembly captivates the bolt onto the work piece, while providing a positive hold out of the bolt.

  • Patent number: 8506226
    Abstract: A security screw formed by a cylinder part divided in two parts in the threaded area with a division line in a partial way of the axial axle or very close to it. In one of these parts a cylinder area has been removed, coaxial (max. eccentricity: 1% of the radius of the thread), with the result that both parts can be moved between themselves, with the thread lined up or not lined up depending on the function of the angle position. Depending on the removed area position, the nut can be threaded or unscrewed. In addition, the nut can be unblocked by immobilizing these parts in the corresponding angle position according to the lining up of the threads.

  • Publication number: 20130164098
    Abstract: A mounting device includes a mounting piece and a mounting member. The mounting piece defines a stepped hole and includes a top surface, a bottom surface, and a blocking ring in the stepped hole. The mounting member is rotatably mounted in the stepped hole and includes a threaded portion. The blocking ring is between the top surface and the bottom surface. When the mounting member is moved towards the bottom surface, the threaded portion extends out of the bottom surface and locks into an object to secure the mounting piece to the object. When the mounting member is moved towards the top surface, the threaded portion is retracted back to the stepped hole, and the blocking ring prevents the mounting member from moving out of the mounting piece.

  • Patent number: 8465241
    Abstract: A method for making composite fasteners includes the provision of a mold containing an elongated cavity having a long axis and the shape of the fastener body, an elongated insert comprising a plurality of long, interwoven or intermingled first reinforcing fibers, and a hardenable liquid matrix that may include a plurality of short, second reinforcing fibers suspended therein. The insert is placed in the cavity such that the long reinforcing fibers are disposed generally parallel to the long axis of the cavity. The mold cavity is then filled with the liquid matrix such that the short reinforcing fibers are distributed generally uniformly throughout the mold cavity, and the liquid matrix of the suspension is then hardened so as to form a hardened fastener body encapsulating the first and second reinforcing fibers. The molded fastener is then removed from the mold, either for immediate use or for subsequent processing.
