A retainer comprises first and second legs extending away from a base wall. In one embodiment, the first leg includes a dimple array surrounding an aperture and projecting from an inboard surface of the first leg. In another embodiment, the first leg has a necked portion having a set of first shoulders extending away from a first base, and a first apertured portion extending away from the set of first shoulders. The second leg has a necked and stepped portion having a step extending away from a second base, and a shouldered portion extending away from the step and having a set of second shoulders extending laterally outwardly, and a second apertured portion extending away from the second shoulders. The retainer of either embodiment may be coupled to a nut to produce a retainer and nut assembly.

A method of installing a cage nut fastener against a frame member without the aid of tools includes: providing a cage nut fastener having a spring cage and a nut prevented from rotation within the spring cage, wherein the spring cage includes first and second lever arms arranged at opposite sides thereof, each lever arm extending in a rearward direction behind a back wall of the spring cage; applying a compression force upon at least one of the lever arms, without the aid of tools, to manipulate the spring cage to a compressed state; positioning a distal end of each of the lever arms through an aperture of the frame member; and releasing the compression force so that a portion of each of the lever arms presses against an edge of the aperture, thereby securing the cage nut fastener against the frame member.

A clip for a nut clip having a main body comprising an aft reaction boss defining at least a portion of a nut containment channel. The clip further includes a nut retention flange defining at least a further portion of the nut containment channel and connected to the main body by a nut retention flange attachment member spaced apart from the aft reaction boss. A forward reaction wall includes at least a portion of the nut retention flange attachment member facing the nut containment channel, wherein the aft reaction boss comprises an aft reaction wall. The aft reaction wall and the forward reaction wall are configured to be selectably contacted by a nut within the nut containment channel to occlude rotation of the nut.

The present invention provides a floating nut, a battery assembly and a vehicle. The floating nut comprises a limit box defining a cavity located therein and a nut body which comprises an axially extending body and a flange radially extending from one end of the body, wherein the size of the flange is configured to adapt to fit within the cavity; and an outer contour of the flange is configured in the shape of a parallelogram, and the parallelogram is configured to have diagonal lines of unequal lengths. The floating nut, the battery assembly and the vehicle of the present invention have the advantages such as being simple in structure, easy to manufacture and convenient for installation, can be used in a limited space, and can reduce the risk of failure.

An assembly is provided that includes a barrel nut, a barrel nut retainer and a fastener. The barrel nut includes a threaded aperture. The barrel nut retainer includes a one-way installation guide. The fastener is configured to thread into the threaded aperture. The fastener is further configured to pass through the threaded aperture and project into the one-way installation guide when the fastener is inserted into the barrel nut retainer along a first direction.

In accordance with one or more embodiments of the invention, nut restrainers, centering tools, and methods of use are presented, particularly as applied to high strength bolted connections. Nut restrainers may have an interior profile including a circular profile section and a regular hexagonal profile section, a nut inserted into the nut restrainer may have lateral freedom of movement, and the nut restrainer may have a top plane with one or more centering protrusions. A centering tool for positioning a nut restrainer may have a non-circular head section, a cylindrical positioning section, a threaded section, and a cylindrical restrainer positioning section; a method of positioning a nut restrainer coaxial with a bolt hole using the centering tool.

The invention relates to a connection system for connecting at least two plate-like elements, the connection system having a bolt, a nut that corresponds to the bolt and has a screwing channel which extends along a screwing axis and into which the bolt can be screwed, and a cage for receiving the nut, wherein the nut has a foot portion and a head portion adjoining the foot portion along the screwing axis, the foot portion projecting, at least in portions, beyond the head portion in a direction perpendicular to the screwing axis.

A nut plate assembly includes a base plate having base plate openings. The nut plate assembly includes channel fittings coupled to the bottom of the base plate each having a main body with a top facing the bottom of the base plate. Each channel fitting has a nut cap channel at the bottom of the main body aligned with the opening in the main body. The nut plate assembly includes nut caps received in the nut cap channels coupled to the channel fittings and positioned below the bottom of the main body. Each nut cap has a pocket holding a nut to receive a fastener used to secure the base plate to the mounting structure from an exterior surface of the mounting structure through the base plate and the main body of the channel fitting.

A workpiece having a hole formed therein including a sliding nut assembly is disclosed herein. The sliding nut assembly includes a base plate having a top surface, a first portion, and a second portion disposed adjacent the first portion, the first portion receives a first fastener to secure the base plate to the workpiece, the second portion having a first elongated hole and a second elongated hole disposed adjacent the first elongated hole, a nut plate disposed over the base plate, the nut plate having a first hole and a second hole disposed adjacent the first hole, the first hole disposed over the first elongated hole, and the second hole disposed over the second elongated hole, a nut extending upward from the nut plate and over the first hole, and a fastener extending through the second hole and second elongated hole securing the nut plate to the base plate.
