A fastener system incorporated in a structural member, the system including a dual threaded member and an anti-rotational member. The dual threaded member is inserted through a hole in the structural member. The dual threaded member has an engaging feature. The anti-rotational member is coupled to the dual threaded member, and the anti-rotational member is coupled with the engaging feature of the dual threaded member and with the structural member to thereby limit rotation of the dual threaded member relative to the structural member.

A fastener includes a male member having a head and a threaded portion protruding from the head along a longitudinal axis, and a female member having a body portion and a tubular tightening portion extending from the body portion along the longitudinal axis. The tubular tightening portion includes a thread bore receiving the threaded portion of the male member and a plurality of teeth formed on an outer surface of the tubular tightening portion. Further, the male member includes at least one arm extending form the head along the longitudinal axis, and the at least one arm of the male member includes a projection protruding radially inward from the arm and engaging the teeth of the female member.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

A device for securing threaded rod relative to concrete and plywood forms is provided. The device can include a housing with a securement portion and a plurality of plungers to engage with the threaded rod. The securement portion can be slidably received in a base configured to be seated on a setting structure. Fasteners can secure the device to the setting structure. A tapered portion of the housing can engage the plungers to secure a threaded rod.

A captive fastener including a bushing having a body portion and an internal bore extending through the body portion A snap ring is mounted within the internal bore. A fastener having an elongated shaft is mounted within the bore and is adapted to reciprocate within the bore between retracted and extended positions. The elongated shaft has a shank diameter and threads formed on one end of the fastener. The snap ring engages the bolt when the shaft is extended and retracted. The fastener has a shank diameter which is 0.020 inches to 0.060 inches shorter than the bore diameter so that the fastener can be moved laterally within the bore.

A centering screw for aligning two elements, particularly a workpiece and a carrier, relative to each other, the centering screw having a first end section with a first outside diameter and a first length, and a second end section with a second outside diameter and a second length, the first end section having a first thread, at least in sections, and a cone being provided for the centering. In this case, the centering screw has the cone in an intermediate section between the first end section and the second end section, the cone having a diameter changing along the intermediate section, the diameter at an end of the cone facing away from the first end section being larger than the first outside diameter, and the end of the cone facing away from the first end section being assigned an axial stop facing away from the first end section.

A nut adapted to disengage with a threaded bolt, the nut comprising a base portion integrally formed to a top portion. The nut includes a bore positioned along a central axis through the base portion and the top portion, wherein the top portion is tapered between circumference of the base portion and the bore of the top portion. The tapering is at an angle between 0° to 45° relative to the diameter of the base portion; the base portion comprises at least two cavities, wherein the at least two cavities extend vertically into the base portion.
