  • Patent number: 6739813
    Abstract: A plastic encapsulated bolt includes a metallic insert having a head (e.g., a hex head, square head, or other type of deformed head) and a shank. An outer plastic layer encapsulates the metallic insert and forms a plastic encapsulated head and a plastic encapsulated shank. The plastic encapsulated shank can be totally or partially threaded. In one application, the plastic encapsulated bolt is used in combination with a plastic female anchor having an internally threaded portion. The plastic female anchor preferably includes multiple sections. The plastic encapsulated bolt includes a tapered threaded nose that engages the internally threaded portion such that the sections of the plastic female anchor expand outwardly as the plastic encapsulated bolt is threaded therein, causing the anchor to engage in an interference fit with a hole, for example, in concrete.

  • Patent number: 6726417
    Abstract: The clip 1 comprises a hollow bushing 6 with a flange 10 and a shank 11, and a pin 5 with a shank 9 inserted into the bushing 6. The pin shank 9 is inserted into the bushing shank 11 to enlarge the bushing shank 11 so workpieces 2, 3 are connected to each other by the enlarged section of the bushing shank 26 and the bushing flange 10. A guide 13 extending from the end of the bushing shank so the pin shank is inserted into the bushing shank 11 without enlarging the bushing shank is formed in the end of the pin shank 5. The guide 13 has a large diameter section 14 larger than the end of the bushing shank. The diameter of the large diameter section 14 is formed so as to be larger than the diameter of a thick section 26 of the creep-deformed bushing shank when enlarged by the pin shank.

  • Patent number: 6726421
    Abstract: A helical thread insert having a removable tang attached to the front end of the insert, a retention device, and a removal notch located along the rear portion of the insert. The removable tang is oriented radially inward and includes a “V” shaped notch oriented along a bottom of a thread to detach the tang at a specified point. The retention device is located at a rear end of the thread insert and prevents counterclockwise, or removal rotation of the insert by engaging female threads of the bore in which the helical thread insert is disposed. The removal notch is formed along an inner surface of the insert proximal to the retention device to allow a tool to actuate the retention device inward, generally away from the female threads of a parent material, to allow relatively free counterclockwise rotation and removal of the thread insert.

  • Patent number: 6719509
    Abstract: An improved expansion screw and particularly an expansion screw for securely anchoring on various types of solid walls and hollow walls mainly includes a bolt and a nail tube. The nail tube has a front end fastened to a nut, a middle portion formed at least one expansion section which has carved slots formed thereon in an annular manner, and at least one -shaped slot formed annularly between the nut and the expansion section. Each -shaped slot has an expansion flap located therein. Every two neighboring -shaped slots are bridged by a longitudinal connection strip to form a bend section. When the bolt nut at the front end of the bolt is turned and driven to generate an inward compression, the expansion flap is forced to extend outwards and overlap with the annular ring at the front end of the nail tube, and the longitudinal connection strip is bent outwards on the bend section to form a double compression on the inner side of a construction hole in a wall to form a secured coupling.

  • Patent number: 6719512
    Abstract: A harpoon nail having two or more sets of teeth on opposite sides of fingers that deform while penetrating the framing members. The teeth engage with a bottom surface to fasten the framing members together. A piercing nail having sets of teeth on two edges penetrates through framing members and the teeth engage with a bottom surface to fasten the framing members together. A piercing nail with a spring member that deforms as the nail penetrates through framing members engages with a bottom surface to fasten the framing members together. A self-locking nail having two members that move relative to one another when penetrating through framing members fastens the framing members together.

  • Patent number: 6715975
    Abstract: A tension control arrangement including a plurality of cams disposed about an opening that accommodates a bolt to which a nut is intended to be secured. Each of the cams has a contoured outer surface, and each of the cams is rotatably supported such that the contoured outer surface operatively engages both the base and a contact member interposed between the cam and the nut. A lever assembly is operatively coupled to the cams, such that movement of the cams is substantially restricted to rotational motion from a first position in which the nut is engaged with the bolt and tightened by hand until it is seated against the contact member, to a second position in which the bolt is elongated to achieve a predetermined bolt tension.

  • Patent number: 6712574
    Abstract: A quick insertion fastener has an internally threaded first member (“nut”) adapted to be quickly attached and tightened on an externally threaded second member (“bolt”). The nut is formed with a casing with an internal frusto-conical front surface, a plurality of threaded shell segments contained in the casing having external frusto-conical front surfaces which abut the front surface of the casing, a spring member positioned at a rear part of the casing which elastically holds the rear ends of the shell assembly together, and an end retainer provided at the rear part of the casing having a taper for engaging the rear ends of the shell assembly and displacing them radially apart when the shell assembly is displaced axially toward the end retainer by insertion of the bolt. This allows the bolt threads to move without interference past the internal threads of the shell segments.

  • Patent number: 6709210
    Abstract: A fastener having a head and two expandable legs. The fastener further has a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. The sides of the Y-shaped funnel comprise inwardly bent portions which are designed to extend into the slot of an object. The bent portions produce jamming and clamping when an expanding member is inserted through a hole on the head, resulting to highly improved pulling force. The fastener may be used in slots of different widths and may be pulled easily out of the slots, if so desired, in contrast with the fasteners of the present state in the art. Further, the fastener may be used in vehicles to connect one or more parts together.
