    Abstract: A machining fixture counterbore bolt fitting includes a counterbore bolt, (SHCS) screw and jam nut. The counterbore bolt defines an axial bore therethrough, sized to location clearance or sliding fit receive the screw and a counterbore sized to running fit receive a head of the screw and of a depth for the head of the screw to bear on the bottom of the counterbore. The counterbore bolt is threaded through a machining fixture to bring a distal end of the bolt into contact with a surface of a part to be machined, with the axial bore around a screw-threaded bore in a fixture mating surface of the part. The screw is threaded into the screw-threaded bore, holding the part against movement with respect to the fixture. The head of the screw bears on the counterbore bottom, pulling the fixture mating surface against the bolt shaft threaded through the machining fixture.

    Abstract: A mounting device for fastening a sanitary article having at least one support having a support wall that defines a cavity, a first opening and a second opening, wherein the support provides a first support-side stop surface at the first opening and a second support-side stop surface at the second opening, at least one screw, and at least one bearing element with a side wall that extends around a central axis and bounds a receiving space for bearing the screw. The bearing element has at least one first stop surface and at least one second stop surface. The at least one second bearing element-side stop surface is arranged on at least one spring lug. The at least one spring lug and the second bearing element-side stop surface are arranged in such a way that the bearing element is clamped without play between the two support-side stop surfaces.

    Abstract: A rapid installation screw includes radially expanding threads. The screw may include a number of discrete thread segments removably affixed to a distal end of an internal shaft. Initially, the thread segments may together have an outer diameter that allows them to slide into a screw hole without engaging threads of the screw hole. Thereafter, a further downward force on the screw will disconnect the thread segments from the internal shaft so that the internal shaft can move axially down between the thread segments. The diameter of the internal shaft forces the thread segments radially outward into engagement with the threads of the screw hole. The internal shaft further includes ribs radially oriented around the internal shaft to fit in between the thread segments. Rotation of the screw head and internal shaft will exert torque on the thread segments, causing them to rotate as well, thus allowing the thread segments to unscrew from the threaded hole.

    Abstract: A fastener and a method of fastening are provided. The fastener can comprise a first end, an oppositely disposed second end, and an elongate portion intermediate the first end and the second end. The elongate portion comprises a first region adjacent to the first end and a second region adjacent to the second end. The first region extends a distance along the elongate portion and has a first diameter. The second region extends a distance along the elongate portion and has a second diameter different from the first diameter. The fastener comprises a transition zone which extends a distance along the elongate portion and connects the first region and the second region. The transition zone comprises a radiused region and a taper region.

    Abstract: Provided is an L-shaped bolt fastening structure using a hole guard, which is capable of being installed in holes having various sizes. Since an L-shaped bolt is fastened in a state in which a hole guard is mounted on a lower structure, fastening using the L-shaped bolt is applicable to a steel pad having a large hole or a large long hole or a grating in which holes are damaged and have irregular sizes. Since bolts can be installed in holes having various sizes in one direction using the hole guard and the L-shaped bolt, the L-shaped bolt fastening structure using the hole guard has a wide range of applications in a floor in an industrial site and as a hook hanger or the like of an H-beam structure, a ceiling, or a wall structure of a construction site.

    Abstract: A fastener structure includes a fastener having a stem portion and at least one movement portion. The stem portion has a fastening section. The movement portion is formed on the stem portion and has a retaining section. With these arrangements, the retaining section of the movement portion can be detachably assembled to a first object and the fastening section can be then detachably assembled or fastened to a second object. In this way, at least two objects can be connected to and disconnected from one another in a quick and repeatable manner.
