Expandable collet bodies with sectional finger-based anti-rotation features are disclosed. The collet body comprises not only a plurality of gripping finger as a first part of a two-part anti-rotation means (ARM), but also a first part of a two part translation arresting means (TAM), which may or may not be sectional in nature. The TAM prevents over translation of a collet body within the work piece(s), and cooperates with a second part of the TAM associated with a work piece or an auxiliary structure. In this manner, a collet body inserted into a work piece or auxiliary structure will not accidentally be pushed beyond the blind side of the work piece(s) during insertion or initial clamp-up.

A first example box nut retainer includes a support, a fastener sleeve, and a wing. The fastener sleeve defines an opening and extends downwardly from the support. The wing extends from the support and has a top corner between the support and the fastener sleeve.

A fastener system shifting shear stresses away from a collet body and provides clamping action to targeted structures. The fastener system includes feet in the collet body that mate with openings in a sleeve at least partially surrounding the collet body. The sleeve or the collet body includes interior threads that engage with a stud that is configured to extend through the collet body and bend the feet such that they project outward from the sleeve openings in an engaged configuration.

A fastening assembly suitable for being fastened to a substrate with a front face and a first hole. The fastening assembly includes a fastening plate with a second plate with front and rear faces and pierced with a second hole aligned with the first hole. The fastening plate front face is fastened to the substrate rear face. The assembly includes a nut holder with a third plate with front and rear faces and pierced with a third hole aligned with the second hole and a nut fastened to the third plate on the side of the rear face and coaxial with the third hole. The front face of the nut holder is fastened to the rear face of the fastening plate. The fastening plate includes a first fastener that engages with a second fastener of the nut holder to removably fasten the nut holder to the fastening plate.

Disclosed is a rack fastener to engage and retain a first member and hold a second member to the first member. The fastener has two coextensive studs, each having base portions, to install from a back surface of the first member each into separate apertures thereof, such that the studs extend through the separate apertures from a front surface of the first member. A connecting portion connects the two base portions. There is also, a clipping portion extending, directly or indirectly, from one of the base portions, the clipping portion having at least one engagement face to engage a region of another aperture of the first member so that the fastener is substantially prevented from being separated from the first member. The two studs can pass through respective apertures of the second member, and thereafter fasteners can engage each stud to secure the second member to the first member.

A retaining device for attachment of objects to a wall surface includes a main body, a fastening arrangement, and a cover lockable to the main body that arches over the fastening arrangement. The main body has a bottom side, that faces the wall during mounting, and a top side, that faces away and includes a retaining ring. The fastening arrangement includes a fastener and a centering cap which fixes the fastener. The bottom side of the main body has a circular-ring-shaped surface, on inner and outer edges of which, in each case, one closed encircling web is provided which faces away from the bottom side. Two passage openings are provided in the circular-ring surface between the top and bottom sides. When attached, the main body is pressed onto the wall and an adhesive is injected through one of the passage openings until it emerges again at the other passage opening.

Aspects of the present disclosure relate to a terminal fastener for electrically connecting a battery terminal associated with at least part of a traction battery to an electrical circuit of a vehicle, the terminal fastener comprising: a terminal engaging portion configured to engage with the battery terminal; a tool receiving portion configured to receive a tool to fasten the terminal engaging portion to the battery terminal; and insulation configured to cover at least part of the terminal fastener.

A stud-mount insert configured to be releasably retained by a mounting-tab of a wire-tray assembly. The stud-mount insert includes a flange and a body configured to rotate about a longitudinal-axis of a mounting-stud. The flange is configured to overlay an aperture defined by the mounting-tab such that the mounting-stud extends through the aperture into the body. The flange is further configured to engage a top-surface of the mounting-tab proximate a perimeter of the aperture.

Disclosed are fastening systems for coupling a first component to stud, shaft, or the like via a sleeve assembly. The fastening system comprising an upper sleeve component, a lower sleeve component, and a nut. The upper sleeve component defines an upper sleeve opening, while the lower sleeve component defines a lower sleeve opening. The lower sleeve component comprises one or more flexible tabs configured to engage the upper sleeve component via the component opening. The nut is configured to pass through a sleeve opening to engage the stud. The sleeve opening is defined by the upper sleeve opening and the lower sleeve opening.

Systems for positioning and bonding a nutplate to a substrate having an aperture include a nutplate engagement fixture and a temperature sensor retention fixture. The nutplate engagement fixture includes a rigid tube and an elastomeric tube engaged with the rigid tube, the elastomeric tube having an elongated tube sized to provide a friction fit with the aperture and retain the elastomeric tube within the aperture. The rigid tube is operable to engage the nutplate at one end and the elastomeric tube is configured to anchor the nutplate engagement fixture at the aperture and secure the nutplate in contact with the substrate. The temperature sensor retention fixture includes a fixture body sized and configured to engage with the nutplate and at least one passageway within the fixture body sized and configured to allow a temperature sensor to be inserted or embedded therein with an end proximal a surface of the nutplate.
