A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.

A nut fastening clip comprises a substrate, and a sleeve. The substrate has an upper surface, a lower surface, a first lateral side, and a second lateral side. The substrate defines an upper opening. The first lateral side is opposite the second lateral side. The sleeve extends from the substrate. The sleeve defines a lower opening in communication with the upper opening. The sleeve has an outer face and a first anti-rotation plane disposed on the outer side face, adjacent to the first lateral side, and connected to the substrate.

A structure attachment for a hanging support system includes an attachment body and a structure fastener coupled to the attachment body and configured to fasten the structure attachment to a structural support. A rod fastener is coupled to the attachment body and defines at least one threaded opening configured to mate with a threaded rod. The rod fastener is selectively movable relative to the structure fastener to adjust an angle between an axis of the threaded opening and a longitudinal axis of the structure fastener.

A threaded fastener having a prevailing torque feature and a method for forming same includes a barrel having a longitudinal axis. The barrel has a plurality of internal threads, each internal thread including a forward facing surface and a rearward facing surface. A first angle between the forward facing surface and a first lateral axis perpendicular to the longitudinal axis ranges from 20° to 40°. A second angle between the forward facing surface and the rearward facing surface ranges from 80° to 100°.

A locator pin assembly includes a locator pin with a locator portion and a threaded portion and a bracket assembly including a tab portion and a nut portion that receives the threaded portion. A structure includes an opening receiving the locator pin and a slot near the opening that receives the bracket assembly.

An apparatus and method for holding a lug nut. The apparatus includes a base (150), a barrel (140), a lug nut engagement assembly (130), a plunger and a cam guide (170). The barrel (140) is coupled with the base (152) in a manner allowing the barrel (140) to move upwardly or downwardly within the base (150). The barrel (140) has an internal cam track portion (145). The lug nut engagement assembly (130) includes retractable fingers (132). The lug nut engagement assembly (130) is removeably affixed to the barrel (140). The plunger (160) is disposed within a portion of the lug nut engagement assembly (130), the barrel (140) and the cam guide (170). The plunger (160) has a tip for engagement with the retractable fingers (132). The cam guide (170) is disposed and moveable within a bottom portion of the barrel (140). The cam guide (170) has longitudinal rails (172) for engagement with the internal cam track (145) of the barrel (140).

A threaded fastener having a prevailing torque feature and a method for forming same includes a barrel having a longitudinal axis. The barrel has a plurality of internal threads, each internal thread including a forward facing surface and a rearward facing surface. A first angle between the rearward facing surface and a first lateral axis perpendicular to the longitudinal axis ranges from 20° to 40°. A second angle between the forward facing surface and the rearward facing surface ranges from 80° to 100°.

The present disclosure provides an assembly including at least one adjustable coupling mechanism. In one aspect, the first coupling mechanism includes a first component having a central axis parallel to its outside surface. The first component further includes an inside surface defined by a bore formed in the first component along a central bore axis. The central bore axis is offset from the central axis. The first component can be coupled to the assembly, uncoupled, rotated about its central axis, and recoupled to change a distance between the first coupling mechanism and another part of the assembly. The first component further includes a plurality of holes formed circumferentially around the bore bottom and extending through the bore bottom and the bottom surface of the first component that can be used to removably couple the first component to the assembly.

A tool for removal of a spring clip from a nut plate assembly includes an inner sleeve having a first cleat configured to engage a first end of a spring clip and an outer sleeve having a second cleat configured to engage a second end of the spring clip, the outer sleeve being rotatably disposed around a portion of the inner sleeve. The tool includes first and second grip tabs respectively extending radially from a longitudinally extending central axis of the inner sleeve and the outer sleeve. Movement of the first grip tab and the second grip tab towards each other rotates the inner sleeve relative to the outer sleeve, and causes the first cleat and the second cleat to rotate towards each other to engage the first and second ends of the spring clip and to enable the spring clip to be removed from an assembled nut plate.

A sheet metal nut includes a base having a flat planar surface. The sheet metal nut also has a sleeve that extends below the base and includes an inner surface. The sheet metal nut further includes at least two front flanges and at least one rear flange. The at least two front flanges are positioned on an edge of the base and extend to a position directly above the flat planar surface of the base. The at least one rear flange extends away from a rear surface of the base. The sheet metal nut is configured to securely fasten to a bottom side of a component through a single aperture when the bottom side of the component is restricted or inaccessible.
