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.

A fastening module, in particular for connecting two components, is provided. The module includes a housing device that defines a receiving space, a nut device that is arranged so as to be displaceable in the receiving space, and a screw device that is connected to the housing device in such a way that the fastening module is a pre-assembled module.

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 restrainer includes a mobile portion; and a fixed portion. The mobile portion may include at least one cavity configured to accept insertion of a nut and prevent rotation of the nut with respect to the mobile portion.

A honeycomb sandwich panel insert includes a housing defined by two identical halves which when joined together form a distal flange having opposed potting holes, and a central internal bore, integrally formed laterally extending member when joined forms a tight closed distal end of said bore. The honeycomb sandwich panel insert further includes a nut disposed within the internal bore of the housing and configured to float therein.

An insert nut includes a cylindrical portion into which a bolt is removably insertable. An inner periphery of the cylindrical portion includes a first region, a second region and a third region which are provided in the order named from an upstream side to a downstream side with respect to an insertion direction of the bolt at an inner periphery thereof. The first region and the third region include a female screw portion threadably engageable with the bolt. The second region has a minimum inner diameter larger than D1+2×h1×0.3, where D1 is an inner diameter of the female screw portion in the first region at a screw thread position and h1 is a height of a screw thread of the female screw portion in the first region.

Methods and apparatus for retaining a fastener receiver are disclosed. An example apparatus includes a retainer to retain a nut assembly adjacent an object. The retainer includes a first plate defining a first opening. The first plate is to couple to the object. The first opening is to receive a portion of the nut assembly when the retainer is coupled to the object. The retainer includes a second plate defining a second opening and including a first deflectable tab adjacent the second opening. The second plate is to couple to the first plate opposite the object. The deflectable tab of the second plate is to cover a portion of the first opening of the first plate. The first deflectable tab is to deflect to receive and retain the portion of the nut assembly in the first opening when the retainer is coupled to the object.

A spring fastener clip includes first, second, and third strips, each with a corresponding hole therethrough. The clip is bent to form an S-shape, wherein the first strip, the second strip, and the third strip are aligned one with another, and the three holes are aligned one with another. The spring fastener clip further includes a hook extending from the second strip to the first strip and including a tab proximate the first hole. When a substrate is disposed between the first and second strips, the tab hooks over an edge of the substrate and resists flexing of the clip on installation of a fastener.

A mounting structure includes a holding portion with a housing space for a mounting component. The holding portion includes a side wall portion upstanding from a base portion, and a seat portion being continuous with a top of the side wall portion and having a bolt through hole into which a bolt is inserted. A mounting component insertion hole is provided in the side wall portion for inserting the mounting component into the housing space. The bolt through hole abuts on the peripheral surface of the cylindrical portion of the mounting component. A communication portion provides communication between the bolt through hole and the mounting component insertion hole, for allowing passage of the cylindrical portion of the mounting component into the bolt through hole. Restrictions form a narrow portion in the communication portion, the narrow portion being narrower than the outer dimension of the cylindrical portion of the mounting component.

A clip nut 100 has first and second opposed arms 202, 204 extending longitudinally and the second arm 204 includes first and second walls 222, 224 extending transversely of the clip nut, and the first wall 222 includes a first plurality of cavities 234, 236 and the second wall 224 includes a second plurality of cavities 248, 250. A nut 102 includes legs 112, 114 extending into respective cavities. The nut is assembled with the clip nut by putting a leg into a cavity in the first wall and moving the nut toward the second arm to engage a cavity in the second wall.
