A roof antenna for mounting on a roof of a vehicle comprises a base plate, an antenna cap connected to the base plate, a circuit board disposed under the antenna cap and having a plurality of antenna elements and a plug connection, a central dome connected to the base plate and having a screw thread, a star wheel interacting with the central dome, and a first O-ring secured on the central dome. The first O-ring fixes the central dome movably with respect to the star wheel and/or the base plate.

A mounting assembly for securing fixtures to a mounting structure may include a first fastener, a washer, a mounting bracket, and second fastener. The first fastener may be coupled to the mounting structure through a mounting aperture. The washer may be disposed around shaft of the first fastener between a head of the first fastener and the mounting surface. The mounting bracket may be disposed on top of the first fastener. The second fastener may be disposed through the mounting bracket and coupled to head of the first fastener. The washer may be a sealing washer that dispenses liquid sealant under compressive force to moisture-proof the securement of the first fastener to the mounting surface.

A battery installation method in a shelter or cabinet includes responsive to placing one or more batteries in the shelter or cabinet, connecting terminals on each of the one or more batteries to associated terminal plates with associated security screws; and connecting a bracket to a housing in the shelter or cabinet with associated security screws, wherein the bracket spans across the one or more batteries and wherein the bracket comprises raised edges which deter cutting.

The disclosure relates to a vehicle component with a bearing bush system for mounting the vehicle component on a fastening portion of a vehicle. The vehicle component includes a bearing bush which has an internal thread, and a bearing bush receptacle which is configured to at least partially accommodate the bearing bush, wherein the bearing bush is configured to be at least partially shifted in the bearing bush receptacle by means of an interaction between the internal thread of the bearing bush and a bearing screw, in order to enter into engagement with the fastening portion. The disclosure furthermore relates to the use of the vehicle component, and to a method for the mounting of the vehicle component.

An assembly for a coupling together rotatable components according to an example of the present disclosure includes, among other things, a rotor shaft extending along a centerline axis, the rotor shaft defining an inner bore extending from an axial end of the rotor shaft, a gear mounted on an outer diameter of the rotor shaft, a lock nut threadedly engaged with the outer diameter of the rotor shaft such that the lock nut abuts against an axial end face of the gear, and a retainer including a step portion extending from a head portion and including a projection portion extending from the step portion. The projection portion is insertable into the inner bore to bias the lock nut against the axial end face of the gear, and the step portion is dimensioned to establish an interference fit with the rotor shaft along the inner bore. A starter assembly and a method of assembly are also disclosed.

A falsification prevention structure is to prevent falsification of the performance of a turbocharger. A bearing housing of the turbocharger has a flow rate adjustment screw which is operated to adjust a turbine flow rate of the turbocharger. The falsification prevention structure includes a cover member which is fastened to a flange portion of the bearing housing by a fixing bolt and which covers the flow rate adjustment screw, and a cap which is mounted in an irremovable manner with respect to the cover member and which blocks a bolt hole.

An anti-loosening fastener, including a key-bolt-receiving bolt, including a head section to receive at least one tool thereon, a rear cylindrical section disposed on at least a portion of the head section to extend a predetermined distance away from the head section, the rear cylindrical section including a key-bolt-receiving aperture disposed within at least a portion of the rear cylindrical section to receive an external fastener therein, and an internal thread section circumferentially disposed on an inner surface within the key-bolt-receiving aperture, and a key bolt to removably connect to at least a portion of the key-bolt-receiving bolt.

A captive screw, comprising: a screw; a press fit nut, to connect to an opening on a device and to accept a screw, including: a bottom portion, to extend through the opening; a top portion; and a middle portion, wherein the middle portion is smaller in circumference than the top portion and the bottom portion; and a sleeve including a protrusion, wherein the sleeve fits over the screw and attaches to the press fit nut via the protrusion.

An apparatus for securing a panel to a structure is provided. In one embodiment, the fastener includes a fastener having a fastener head and a threaded tail, and the fastener may be disposed through a structure and an external panel. The apparatus also includes a retainer housing positioned on the fastener head, where the retainer housing is detached from the fastener. A spring engaging the fastener and the retainer housing is also included within the retainer housing.
