Abstract: A system for installing and removing a temporary concrete barrier from a bridge deck includes a bolt, a star washer, a flat washer, a two-part sleeve, and a barbed nut. A method of using the system includes the steps of positioning the temporary concrete barrier at a desired location on the bridge deck; drilling a mounting hole in the bridge deck; tilling the mounting hole with epoxy; inserting the barbed nut and two-part sleeve into the mounting hole and epoxy; inserting the bolt into the two-part sleeve and the barbed nut; waiting for the epoxy to set, tightening the system so that the temporary concrete barrier is held in place with respect to the bridge deck; loosening the system and removing the concrete harrier when it is no longer needed; and filling the mounting hole with epoxy after the concrete barrier is removed.

Abstract: A self-locking insert and a linear actuator having a self-locking insert are provided. The self-locking insert includes an insert body having an outer surface, a bore extending through the insert body, the bore defining an inner surface, a self-locking feature configured to engage a holder to retain the self-locking insert in a predetermined position, and a de-lashing feature configured to interference fittingly engage the holder.

Abstract: One or more fastenings can be used to fasten components together, such as housing components on a computing device. Each fastening can include a first opening associated with a first component, a second opening associated with a second component, a floating fastener, and a screw. The floating fastener is inserted into the first opening and/or second opening, and includes a threaded opening therein having a primary axis therethrough. The screw is inserted through first and/or second openings and into the threaded opening in the floating fastener. The screw and threaded opening combination is defined by contact between the screw and threaded opening about a thread surface that is substantially perpendicular to the primary axis, a screw thread return angle of 45 degrees or less, and a thread depth that is less than about triple the float between the major diameters of the screw and the threaded opening.

Abstract: The conduit body assembly includes a metallic conduit body having an open upper end and a metallic cover removably positionable over the upper end. A metallic threaded fastener secures the cover to the body. The metallic fastener includes a threaded post and a nut removably attached to one end of the post. The nut and the post are formed of similar non-corrosive materials so as to resist corrosion therebetween. The nut is removable from the post in an environment where corrosion between the metallic fastener and the conduit body and cover prevents removal of the threaded fastener therefrom. Removal of the nut from the threaded post permits removal of the cover from the conduit body.

Abstract: A U-nut fastener assembly includes a U-nut fastener including a first arm member, a second arm member formed unitarily with the first arm member, a bite portion formed unitarily between the first and second arm portions such that the first arm member, the second arm member, and the bite portion are oriented to form a substantially U-shape. The nut includes a single helical thread having a proximal end and a distal end that are separated by a longitudinal gap. The U-nut assembly also includes a fastener device adapted to be received within the U-nut fastener. The single helical thread has a proximal end and a distal end and a gap disposed between the proximal and distal ends. The U-nut assembly is molded from a plastic material to include an anti-reverse feature that inhibits the fastener device from loosening with respect to the U-nut fastener. The anti-reverse feature is also adapted to provide a tactile indication to an operator installing the U-nut assembly.

Abstract: A weldable nut assembly includes a plate body and a nut body. The plate body has top and bottom sides, and is formed with an installation hole, and a plurality of welding portions that protrude from the bottom side of the plate body. The nut body includes a nut portion that abuts against the top side of the plate body and that is in spatial communication with the installation hole, an upper annular flange that abuts against the top side of the plate body, and a lower annular flange that extends downwardly and coaxially from a bottom side of the nut portion, that extends into the installation hole, and that is machined so as to abut against the plate body. The lower annular flange has a plurality of teeth that abut against the plate body and that cooperate with the upper annular flange for clamping the plate body therebetween.

The first member is prefabricated to include a lip for partially overlapping a side wall and a bevelled edge. The plurality of building members may include a plurality of precut studs and rafters and the first member further may comprise a plurality of notches in spaced-apart relation, the notches being sized to permit the insertion of the studs therein.

Abstract: A safety bolt having a headed end, a shank, and a second end with means near the second end to hold the bolt in a hole in a workpiece. An axial passage opening into the second end intersects a laterally-extending passage spaced therefrom, and a dog fits in the laterally-extending passage wherein it is laterally reciprocable so as to be extendible beyond the maximum diameter of the shank or to be entirely retracted within it. A cam member having a pair of oppositely facing cam surfaces is axially slidable in the axial passage. The dog has a pair of followers one on each side bearing against oppositely directed cam surfaces whereby the lateral position of the cam is uniquely a function of the axial position of the cam member. Bias means is provided to bias the cam member to a position corresponding to maximum extension of the dog.
