A rivet sleeve of a blind rivet for connecting at least one die-head-side component to a closing-head-side component, the rivet sleeve having a sleeve shank including a sleeve shank end. An elastic sleeve die head is arranged at an end of the sleeve shank opposite the sleeve shank end for ensuring a minimum clamping force between at least the die-head-side component and the closing-head-side component in a closed state of the blind rivet, the sleeve die head. The sleeve die head extend around the sleeve shank radially around the extension axis of the sleeve shank. At least two recesses spaced a distance apart in the lateral surface of the sleeve die head.

A blind rivet-nut having an annular-flange-like setting head and a hollow shaft for securing a blind rivet-nut in an opening of a carrier. The hollow shaft has a free end having a threaded portion for receiving a threaded element of a tensioning tool. A clamping portion adjacent to the setting head forms a bead-like deformation when the tensioning tool is used to clamp the carrier between the bead-like deformation and the setting head. A threadless shaft portion is formed between the clamping portion and the threaded portion. The threadless shaft portion is threaded by a thread self-rolling or thread self-tapping fastener. The fastener is received in a positive-locking manner when the fastener is screwed into the thread formed on the previously threadless shaft portion. A method is also disclosed for securing a component to a carrier by a blind rivet-nut.

A rivet for fastening workpiece members, the rivet including a body comprising a shank extending in a first, longitudinal direction and a head extending in a second, substantially transversal direction, a bore being defined through the shank and the head of the body; and, a stem comprising a main longitudinal portion arranged for insertion into said bore, and an enlarged portion arranged for radially expanding the shank when the enlarged portion is forced into said bore to fasten the workpiece members; the rivet being configured for insertion into respective apertures formed in the workpiece members; and the rivet being further configured such that when the workpiece members are fastened, the head of the body of the rivet is displaced relative to the shank to engage with the stem to lock the stem in place relative to the body and/or the workpiece members.

The invention relates to a fastener (10) for the temporary assembly of structures (12, 13), comprising: a tubular body, extending between a first end and a second end comprising at least two longitudinal tabs (46); a hooking element, rotationally prevented and capable of sliding axially in the body, said fastening element comprising a tubular base and a plurality of elastic clips (62) connected to one end of said base, each clip comprising a hooking spur (74); a driving device for the fastening element; and a spreader (26) fixed relative to the body, the plurality of elastic clips being positioned around said spreader. The tubular base (60) comprises two longitudinal grooves in an outer surface; and the fastener is configured so that each tab (46) of the body is capable of sliding axially in one of said grooves.

A blind rivet for establishing a screw connection between a support component and a fastening part has an elastic outer body and a metal bushing arranged therein. The outer body is at least partially surrounded by a fixing sleeve which fixes the outer body on an end portion in the metal bushing.

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 single groove single-sided fastener comprises: a rivet consisting of a rivet head, a polish rod, a locking groove, a tail pulling groove and a tail tooth in sequence, and a lantern ring consisting of a sleeve and a dead head; a tail of the rivet is of a single groove short-tail structure, a ratio of a length of the tail pulling groove to a total length of the tail tooth is 0.1˜1.5, an included angle between a bottom generatrix of the tail pulling groove and an axis of the rivet is −30°˜0°, two axial ends of the bottom of the tail pulling groove and the tail of the tail tooth are of a fillet transition structure, a ratio of a length of a straight part of the tail tooth to the total length of the tail tooth is 0.1˜1.

A bonding washer for making electrical connection between two metal pieces that are to be mechanically fastened together. The washer, to be interposed between the two metal pieces, may be constructed so as to fasten to one of the pieces before the two pieces are joined. Teeth on the washer, positioned at right angles to the plane of the washer, are forced into each of the two metal pieces when the fastener is tightened, making electrical connection between the two metal pieces.

A purpose of the present disclosure is to provide a clip including a grommet and a pin, which does not degrade design quality and allows the clip to be removed easily from members to be attached without causing damage. The grommet is configured to be inserted into attachment holes of the members to be attached, and includes a grommet hole into which a pin is to be inserted. Depending on an insertion position of the pin relative to the grommet, the grommet undergoes elastic deformation to allow the members to be attached to each other or detached from each other. A flange portion of the grommet has an engagement hole so that the clip can be removed from the members by engaging a tool with the engagement hole.
