Patent number: 11655842Abstract: Disclosed is a fastener assembly comprising at least one of a bolt member and a nut member; and a drive element adapted for engagement by an installation/driving tool, said drive element comprising a body. The body of the drive element is joined either to the bolt member or to the nut member by means of an interposed interlayer structure, the interlayer structure being adapted to fracture in torsional shear and/or tensile stress in response to a relative rotational and/or tensile force applied to the drive element with the installation/driving tool.Type: GrantFiled: December 17, 2018Date of Patent: May 23, 2023Inventor: Jürgen Rösing

Patent number: 11512729Abstract: Disclosed is a fastener assembly comprising: a bolt member, comprising a bolt head and a shank, at least a part of which is screw threaded; a nut member for threaded engagement with the shank; a first drive element allocated to the bolt member and a second drive element allocated to the nut member, each drive element comprising a body and adapted for engagement by a corresponding tool. The body of the first drive element is joined to the bolt member by a first interposed interlayer structure. The body of the second drive element is joined to the nut member by a second interposed interlayer structure. The first interlayer structure is adapted to fracture in response to relative rotational and/or tensile force applied to the first drive element. The second interlayer structure is adapted to fracture in response to relative rotational and/or tensile force applied to the second drive element.Type: GrantFiled: December 14, 2018Date of Patent: November 29, 2022Assignee: Fairchild Fasteners Europe—VSD GmbHInventor: Jürgen Rösing

Patent number: 11408454Abstract: The invention relates to a fastener (10) for attaching together workpieces (50a, 50b) having aligned holes therethrough, the fastener (10) comprising a shank portion (11) and a head portion (13) provided at one end of the shank portion (11), the diameter of the shank portion (11) and/or of the head portion (13) being selected such that the fastener (10) can be installed in the aligned holes in close tolerance. The fastener (10) further comprises an oversizing structure (20), said oversizing structure (20) being firmly bonded to at least a part of the shank portion (11) and/or the head portion (13) in order to oversize at least the part of the shank portion (11) and/or the head portion (13) such as to allow the fastener (10) to be installed in aligned holes (60a, 60b) having a diameter larger than that required for the fastener (10) without the oversizing structure (20).Type: GrantFiled: May 4, 2018Date of Patent: August 9, 2022Assignee: Fairchild Fasteners Europe—VSD GmbHInventors: Jürgen Rösing, Meindert Büsse, Jan Dohmeyer, Sead Dzebo, Torsten Timpe
