Potted-in inserts are provided for use as attachment points for securing objects to sandwich panels. The potted-in inserts comprise a shaft having a first outer diameter, a first end having a second outer diameter that is greater than the first diameter, a second end having a third outer diameter, and an inner bore extending through the first end, the shaft, and the second end. The inner bore having an inner diameter. A lattice structure is between the first end and the second end and in an area adjacent the shaft between the first diameter and the second diameter. The lattice structure is fixed to the first end, the second end, and/or the shaft. The lattice structure has a plurality of interconnected unit cells each comprising struts connected at nodes to define voids between the struts. The voids are sufficiently large to receive therethrough a potting compound.

A hollow-cylindrical preloading cartridge of an installation tool of a wire thread insert has a mandrel channel extending within the preloading cartridge, in which an assembly mandrel with an installation end and a drive end is guided in an inner mandrel guiding thread. The cartridge has an outer wall which encompasses the mandrel channel at least partly with a radial positioning window adjacent to a first axial end of the preloading cartridge facing away from the drive end of the assembly mandrel, through which a wire thread insert is positionable on the assembly mandrel. At least one first tactile detection unit projects beyond a ring-like front side of the cartridge on the first axial end and is offsetable parallel to a longitudinal axis of the cartridge, wherein an axial offset of the at least one tactile detection unit can be detected with a first detection sensor of the cartridge.

A fastening insert made of plastic with a T-shaped configuration consisting of an insert disc and a hollow cylindrical shaft fastened to the insert disc. The insert disc has a plurality of passage openings arranged off-center, at least one of which has an edge projection extending circumferentially continuously or circumferentially in sections, which is formed as toothing and extends on one side or both sides beyond the respective fastening side of the insert disc. This toothing ensures an additional form-fit connection or fixation of the fastening insert in a preferably fiber-reinforced composite material.

A multipart socket-like glue-in retainer which is fastenable in a component opening in an adhesive manner in a component opening and which is configured in at least two parts and thus in an opening manner in radial direction due to an axial separation, so that only before a gluing-in of the glue-in retainer in a component opening, a functional insert is arrangeable in the glue-in retainer and after the gluing-in of the glue-in retainer in the component opening, the functional insert is retained inseparably in the glue-in retainer.

A fastening device for fastening at least two panels or flanges to each other is disclosed. The device comprises a male member, a female member and a washer. The male member is inserted into and at least partially through aligned slots in the panels or flanges. The male member includes or houses a first securing component. The female member defines an opening generally complementally shaped to the projection of the male member. The male member and the female member are configured to receive the at least two panels or flanges between them when the projection is received in the opening. The washer mates with the female member such that displacement of the washer relative to the female member towards the male member is substantially prevented. The device further comprises a second securing component configured to mate with the first securing component and to secure the washer against the female member.

The present disclosure provides an insert of a fastening system. The insert includes (a) a flange, (b) a sidewall extending from the flange and defining a first through-hole, (c) a nut including a first end and a second end and defining a second through-hole, wherein the second end of the nut comprises two or more gripping fingers extending longitudinally from the first end of the nut and separated by two or more slots, and wherein the two or more gripping fingers are flexible in a radial direction and biased to converge inward such that the second through-hole is tapered from the first end of the nut to the second end of the nut, and (d) a stopper coupled to an interior surface of the sidewall and positioned between the first end of the nut and the flange.

A fastener for attaching a first part and a second part includes a body comprising a first body portion, a second body portion, a flange arranged between the first body portion and the second body portion and extending radially outwardly from the body. A bore extends in an axial direction through the body and including an inner surface with threads. A plurality of splines extend radially outwardly from the second body portion and is configured to prevent rotation when the second body portion is inserted into an opening in the first part. An opening to the bore at the second body portion defines a concentric edge and an inclined plane extending from the concentric edge.

A component has a base bushing, which has a first axial end and an opposite second axial end and a first inner diameter, wherein the base bushing is equipped with a first internal thread with a first thread direction, and has a fastening bushing, which has a third axial end and an opposite fourth axial end and a second inner diameter. The fastening bushing is equipped with a second internal thread with a second thread direction which is opposite to the first thread direction, wherein the second inner diameter is smaller than the first inner diameter and the base bushing and the fastening bushing are separate elements and are arranged coaxially with respect to one another in the component. Alternatively, the base bushing and the fastening bushing are formed as a single piece.

An insert intended to be assembled in a hole in a sandwich panel including a hollow cylindrical body having a flanged end deformable by a placement tool allowing mechanical connection by deformation with a surface skin of the sandwich panel is provided. The insert includes an anchoring stem in the continuation of the cylindrical body as well as an internal tube intended to collaborate with the placement tool. The anchoring stem has at least one circumferential groove and a peripheral rib, the circumferential groove and the peripheral rib each having a transverse profile that is rounded so as to be able to collaborate with a curable substance.
