A device for adjusting the height of a motor vehicle body (3), including an actuator (1) for actuating a vertically adjustable spring seat of a suspension spring (15), characterized in that a pin (4) is provided for connecting the device to the vehicle body (3), an actuator side pin section (10) extends through a support eye (6) in a support plate (7) of the actuator (1), and an elastomer support (2) is disposed at least on the face of the support plate (7) facing the vehicle body, between the support plate (7) and a flange (9) provided on the bolt (4).

Watertight fastening devices and systems and methods for the employment thereof are disclosed. The disclosed watertight fastening device includes a head, a shank extending away from the head toward a distal end, and a cover extending outwardly and away from the head in the direction of the shank and defining a hollow region between the shank and an inner surface of the cover. The watertight fastening device may be used in conjunction with a solar power installation system that includes a base plate configured to be positioned against an installation surface. The base plate includes an aperture for receiving the shank of the fastener and protrusion surrounding the aperture configured to be received in the hollow region of the fastener, thereby providing an enhanced barrier against moisture reaching the installation surface.

A double ended dual attached fastener includes a first portion having a stud bolt, a second portion configured to anchor to a panel member, and a flange nut partitioning the first end and the second end. The flange nut includes a flat interior annular surface facing the second portion. The flange nut includes a plurality of radially spaced weld projections extending toward the second portion. The weld projection includes a material that amendable to form a weld joining the flange nut to a panel member through which the second portion is inserted. The second portion defines a fastener selected from a group consisting of a self-tapping friction screw, a self-piercing rivet, and a swage bolt.

Presently disclosed is a standoff fastener for use in a compound floor structure. The threaded fastener includes a threaded standoff portion designed to accept a nut which has a diameter larger than a head portion of the standoff fastener. The head portion is located centrally within the fastener in order to reduce a tendency of the fastener to pivot within a driver during the fastening process.

A fastening member with a plurality of fastening portions includes two or more fastening portions. The fastening portions are configured to be fastening connected to a first object or to be fastening connected to a second object, and have the same or different fastening connection directions or the same or different fastening connection positions. Thus, the fastening member may be disposed at a third object, and be fastening connected to the first object and the second object by the fastening portions, respectively, so as to complete coupling and separation of at three objects, achieving the effect of repeated quick coupling and separation.

A base plate assembly is provided for supporting a structural member on a floor surface. The base plate assembly has a substantially planar base plate, having one or more holes through the base plate. There are also one or more supports to support the base plate above the floor surface, forming a cavity between the base plate and the floor surface. There are one or more bolt retainer assemblies each having a bolt, associated with one of the one or more holes. Each bolt retainer assembly has an engaged orientation retaining the bolt through the hole and an retracted orientation retaining the bolt within the cavity and not through the hole.

Methods and systems are provided for a fastening assembly. In one example, the fastening assembly includes a vibration dampening element, a two-piece insert, a lower portion, and a fastener configured to engage with the two-piece insert and the lower portion of the assembly. The fastening assembly may be at least partially assembled during manufacture of components to be coupled via the fastening assembly, allowing the components to be readily coupled during final installation of the fastening assembly.

Presently disclosed is a standoff fastener for use in a compound floor structure. The threaded fastener includes a threaded standoff portion designed to accept a nut which has a diameter larger than a head portion of the standoff fastener. The head portion is located centrally within the fastener in order to reduce a tendency of the fastener to pivot within a driver during the fastening process.

A floating connection fastening system employs a semi-flexible floating bushing having a sleeve with an axial slot which captures a fastener having a head, an unthreaded shank portion, a threaded portion and an intermediate reamer. An adapter mounts to the bushing/fastener assembly and receives a driver bit. The adapter defines an offset clearance. The floating connection is installed by driving the fastener through a non-load bearing member so as to form a bore and embed the fastener into a load bearing member. The floating bushing has a flange which engages the surface of the non-load bearing member. The installation may be performed in essentially a one-step procedure.

Disclosed is a resilient fastening arrangement (200) for construction of a vibration damping assembly (100) comprising at least a first structure (110) and a second structure (120). The resilient fastening arrangement (200) comprises a first part (210) for fixation to the first structure (110) of the assembly (100) and a second part (220) for engagement with the second structure (120) of the assembly (100). The arrangement (200) further comprise a third part (230) arranged to resiliently connect the first part (210) to the second part (220) along an arrangement axis (D). The third part (230) comprises a resilient member arranged to at least partially extend within a hole (125) of the first structure (110) and/or of the second structure (120) of the assembly (100). Further resilient fastening arrangement (200), vibration damping assemblies (100) and a method for constructing a vibration damping assembly (100) are disclosed.
