A rivet nut (“rivnut”) installation method and a rivnut structural configuration are disclosed that can be implemented separately in conjunction with one another to serve as an anchor in and/or a workpiece at an installation location. The rivnut installation method involves inserting a rivnut onto an externally threaded mandrel, rotating the mandrel while a free end of the mandrel is in contact with the workpiece, and driving the free end of the mandrel and the rivnut through the workpiece while continuing to rotate the mandrel. The method is particularly useful when the workpiece includes one or more substrate layers composed of a low ductility material such as a polymer composite. The rivnut structural configuration includes the incorporation of an external threading onto at least a portion of a hollow shaft of the rivnut.

A connection between at least a first component A and a second component B with an attachment arrangement with tolerance compensation between the first component A and the second component B. The entire connection is fixated via a blind rivet which is not non-destructively detachable while a compensating sleeve spans a distance between the first component A and the second component B.

The present invention is equipped with a shaft 11; a bolt 10 having a head 12 with a diameter larger than that of the shaft at a first-side end of the shaft; a first sleeve 20 having a cylindrical shape through which the shaft is inserted, a first-side end of which abuts on the head and the other-side end of which enters a fastening hole 103; a washer 30 having a tubular shape through which the shaft is inserted, arranged adjacent to the first sleeve on the other-end side of the first sleeve so as to be in contact with a member to be fastened 101, a first-side end thereon entering the fastening hole; and a nut 40 that is placed adjacent to the washer and screwed into the bolt; wherein tapered surfaces 310 and 32a, which are tapered toward the other-side end of the first sleeve, are formed on the washer in contact with the member to be fastened and on the first-side end thereof, respectively; a tapered surface 21 whose diameter increases toward the first-side end of the washer is formed at the other-side end of the first sleeve; and the other-side end of the first sleeve and first-side end of the washer are in contact with each other on both tapered surfaces.

A tool for installing a blind fastener including a core bolt and a core nut is provided. The tool includes a driving member, a collet driven by the driving member for engaging the core bolt, and an external sleeve for holding the core nut and preventing the core nut from rotating during installation of the blind fastener. The external sleeve is movable between a first position in which the external sleeve is driven by the collet to rotate with the collet and a second position in which the external sleeve is stationary despite rotating action of the collet.

A tool for installing a blind fastener. The tool includes a retention member and a gripping member that defines a longitudinal axis and is moveable relative to the retention member along the longitudinal axis, the gripping member further defining a receiving cavity that is elongated along the longitudinal axis, an axial opening into the receiving cavity, and a radial opening into the receiving cavity. The tool also includes a contact element at least partially received in the radial opening and a locking collar moveable relative to the gripping member along the longitudinal axis between at least a first position and a second position. In the first position the locking collar engages the contact element and urges at least a portion of the contact element into the receiving cavity. In the second position the locking collar is disengaged from the contact element.

Disclosed is a method of manufacturing a deformable sleeve nut that includes selectively strain hardening only a first portion of a material blank while not strain hardening a second portion of the material blank, then, after strain hardening the first portion of the material blank, internally threading the first portion of the material blank to define a nut portion and machining the second portion of the material blank to define a deformable sleeve portion that includes an end portion and a bulbing portion positioned between the end portion and the nut portion, where the bulbing portion is constructed to bulb outwardly and form a load bearing flange when the bulbing portion is compressed between the end portion and the nut portion. Also disclosed is a deformable sleeve nut made with this process.

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.

A fastener for securing at least a first component and a second component together, the fastener comprising: a securing portion adapted to be secured to the first and/or the second component, and a guiding portion adapted to be guided by a manipulator or a tool in order to set the securing portion in the first and/or the second component, wherein the securing portion and the guiding portion form a one-piece element made of one unique aluminium alloy having a composition between 0.03 and 0.55 wt % Scandium.

An insert to be crimped on a support includes a body having a shank extending along a longitudinal axis and including a crimping section configured to deform into a crimping bead to crimp the insert on the support, and a flange presenting a surface facing the crimping section and extending along an axis perpendicular to the longitudinal axis, the flange having a constant thickness and presenting a fold forming a groove situated on the surface and designed to receive a seal. A fixing part includes the insert and a seal housed in the groove of the insert, and a fixing assembly includes the fixing part and a support on which the fixing part is crimped.

A blind fastener has a sleeve and a pin. The sleeve has a shank with a shank bore and a head with a head bore smaller than the shank bore. The pin has a pin installation portion with a proximal end portion and a distal end portion. The pin also has a breakaway portion with a pin grip, and a pin break groove between the installation portion and the breakaway portion. The pin further has a grip portion at the proximal end portion of the pin installation portion and directly adjacent to the pin break groove. In a pre-installation configuration, the grip portion is in the sleeve bore. In an installation configuration, the grip portion is in the head bore and forms a friction fit with the head bore to prevent the installed sleeve from inadvertently coming free of the installed pin.
