A system includes a washer, a nut, a retainer structure, and a gasket. The washer has a bore extending between a distal end and a proximal end. A first section of the bore extends from the distal end to a shoulder portion. A second section of the bore extends from the shoulder portion to the proximal end. The shoulder portion defines an aperture. The nut is configured to be received in the first section of the bore. The nut includes a threaded bore configured to threadably engage a threaded shaft of a bolt. The retainer structure is configured to axially retain the nut in the first section of the bore of the washer. The gasket has a through-bore axially aligned with the bore of the washer and the threaded bore of the nut. The gasket is configured to be axially retained in the second section of bore of the washer.

A method and apparatus for fastening structures. A first end of a body is placed into a hole on a first side of the structures. The body has an outer surface with a noncircular cross-section. A nut element is positioned on a flange at a second end of the body. A bolt is moved into a channel at the first end of the body towards the nut element on the flange on the second end of the body on the first side the structures. The bolt and the nut element are fastened to each other.

A clip nut, including a clip. The clip has a first retaining device, a second retaining device, and a connecting device, which connects the first retaining device to the second retaining device. The distance between the retaining devices is variable. The extension of the first and second retaining devices substantially define an x axis and the extension of the connecting device substantially defines a z axis. A y axis is perpendicular to the x axis and the z axis. The clip nut also includes a nut, which is arranged on the second retaining device such that an axis of the nut is aligned parallel to the z axis and/or perpendicular to the x axis. The axis of the nut is pivotable from the position of the axis of the nut parallel to the z axis and/or perpendicular to the x axis about the axis in an xz plane such that the parallelism of the axis of the nut with respect to the z axis and/or the perpendicular position of the axis of the nut with respect to the x axis is abandoned. A seal facing the first retaining device is provided on the nut, and a component, to which the clip nut is fastened, directly contacts the first retaining device and the seal.

Fastener assemblies and nut plate assemblies include a plate member, a shell member and a floating nut disposed within the shell member and defining a bore configured to receive a threaded fastener. The fastener assemblies and nut plate assemblies also include at least one magnetic component disposed within the shell member and configured to switch the nut plate assembly between a locked configuration and an unlocked configuration

A cage nut fastener, capable of installation against a frame member without the aid of tools, includes a spring cage and a nut retained within a space defined by the spring cage and prevented from rotation therein. The spring cage includes a back wall with a wall aperture therethrough, a cage arm extending in a forward direction from a side of the back wall, and a lever arm disposed at a side of the back wall that is opposite the cage arm. The nut includes a nut aperture therethrough that is generally aligned with the wall aperture of the back wall. The lever arm includes an extension portion that extends in a rearward direction behind the back wall of the spring cage. Application of a compression force upon the lever arm, without the aid of tools, manipulates the spring cage to a compressed state that facilitates positioning of a distal end of each of the cage arm and the lever arm through an aperture of a frame member so that, upon release of the compression force, the spring cage and the nut are secured against the frame member.

A fastener includes a base member; a first member, on the base member and having a through bore; a second member, on the base member and spaced from the first member to form a receiving portion to receive a panel structure, including an aperture defining an internal surface, the internal surface including at least one stop member protruding radially inwardly, and a nut member, coaxially aligned within and frangibly connected to the internal surface, including at least one block member protruding radially outward from an outer surface of the nut member to stoppingly engage with the at least one stop member. During use, the nut member moves from a first position, where the nut is frangibly connected to the internal surface, to a second position, where the least one block member abuttingly engages with the at last one stop member.

A nut clip is disclosed. The nut clip may have a nut and a clip. The clip may have a forward reaction wall and an aft reaction wall structured to react tightening and loosening forces associated with the nut and to facilitate caging of the nut.

A bushing assembly comprises a bushing element having a first surface, which is adapted to come into contact with a shoulder, and a threaded hole, which defines and axis and is adapted to be engaged by a screw; and a cage element, which is fitted around the bushing element so that the bushing element is supported and is floating; the cage element is adapted to be fixed to the shoulder and is provided with at least one opening; the opening defines an end abutment of the cage element; the bushing element comprises at least one stop portion, which engages the opening with an angular clearance and is movable around the axis at least between a first angular position, in which the stop portion is spaced apart from the abutment, and a second angular position, in which the stop portion is in contact with the abutment so as to prevent the bushing element from rotating past the second angular position; the stop portion is defined by an appendage element, which is distinct from the surface and the surface is circular.

Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.

The present invention relates to a mounting device for mounting a nut on a screw of a battery assembly, comprising a mounting body having a receptacle extending continuously in a longitudinal direction for receiving the nut, and a holding element extending radially inwardly in the receptacle for holding the nut in a pre-mounting position distanced from the screw as well as a battery assembly comprising the mounting device.
