  • Patent number: 11761067
    Abstract: Provided herein are techniques for making low-carbon steels with high surface hardness. A technique includes heating a low-carbon steel precursor material in a furnace to form molten steel material, increasing the free oxygen content of the molten steel material to a predetermined level, and then solidifying the molten steel material having the predetermined oxygen level to produce a steel structure by cooling the molten steel material at a predetermined cooling rate. The predetermined oxygen level and the predetermined cooling rate are effective to produce the low-carbon steel with a high surface hardness. The low-carbon steel may have inclusions smaller than about 1 ?m.

  • 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.

    Abstract: A fiber reinforced plastic bolt (FRP) and a method for producing the same are disclosed. The FRP bolt is useful in the industrial areas which require a bolt having electric-insulation, anti-corrosive, thermal-insulation, and non-magnetic properties. The method for producing the FRP bolt includes the steps of: winding a prepreg around a surface of an internal body, wherein the internal body includes a first reinforcing fiber which is unidirectionally aligned along the axis of the bolt, and a synthetic resin which is impregnated into the first reinforcing fiber, and the prepreg includes a second reinforcing fiber and a thermosetting resin which is impregnated into the second reinforcing fiber; forming a fiber reinforced plastic round bar by heat-hardening the prepreg; and forming a screw thread on the surface of the fiber reinforced plastic round bar.

  • Patent number: 8556556
    Abstract: A fastener with a breakaway and methods of using the same. In one embodiment the fastener is a screw having a head and elongated stem, adapted to be easily manipulated by a user when using the screw as a fastener in a hinge or joint. A means of holding a screw by providing a breakaway tab or non-threaded second portion of the elongated stem which can be used to align and insert the screw into a screw hole in the process of engaging threads in the screw hole with threads of the screw. After engaging the threads in the screw hole, such as after the screw has been essentially completely inserted into the screw hole, the breakaway tab or non-threaded second portion of the elongated stem of the screw may be broken off at a breakaway and discarded.

  • Patent number: 8511958
    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.
