A fastening system has a fastening element and at least one fastening device having a flanged housing, a closure element, a hollow-sphere element and a spherical insert. The hollow-sphere element pivots about a first pivoting axis relative to the flanged housing, while the spherical insert pivots about a second pivoting axis in the hollow-sphere element. First engagement means in an opening of the spherical insert are of complementary design to second engagement means of the fastening element. The first and second engagement means are designed such that, in a first rotational position, the fastening element can be inserted freely into the opening and, in a second rotational position, the first and second engagement means engage in one another.

A block and bolt connector comprises a block having an aperture with a lower opening and an upper opening which is smaller than the lower opening. The aperture extends through the block from the lower opening to the upper opening, and has a first portion and a second portion. A bolt has a head portion which passes through the lower opening but not the upper opening, and a shaft which may pass through the lower opening and the upper opening. The head portion of the bolt is received within aperture of the block and the shaft extends at least partially outside of the block beyond the upper opening. The first and second portions of the aperture are configured so as to permit selected movement of the bolt within the aperture relative to the block.

An auxiliary side view mirror assembly is mountable to a cover portion of a conventional side view mirror as may be preinstalled on an outside of a variety of different automobiles. The assembly comprises a base configured to clamp onto a portion of the conventional side view mirror cover. A frontward portion of the base may form a ridge defining a mounting surface configured to retain a mirror. An auxiliary mirror may be set in a frame comprising a back side opposite a reflective surface of the auxiliary mirror, and an arm, securable to the mounting surface, may extend outward from the back side of the frame. When coupled to the mounting surface by way of the arm, the auxiliary mirror may be adjustable, relative to its mounted position, according to the needs of the driver and may be operative to reduce blind spots otherwise experienced by the driver.

A side tensioning assembly for retaining screen media to the side plates of a vibrating-type screening machine includes a support structure for supporting the screen media and a tensioning rail mountable to at least one side plate. At least one bolt assembly is provided for fastening the tensioning rail to at least one of the side plates. Each bolt assembly including a bolt connectable to the tensioning rail, at least one of side plates and at least one bolt engaging structure on a surface of the side plate. Each bolt engaging structure includes a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position.

An aircraft removable equipment fitting device, the aircraft comprising a structure to which the removable equipment is configured to be attached. The aircraft removable equipment fitting device includes a first coupling configured to be joined to the aircraft structure, a second coupling configured to be joined to the removable equipment and to be coupled to the first coupling, and a fastener configured to tighten the removable equipment and the second coupling to the first coupling so that the removable equipment is fastened to the aircraft structure.

A floating connector includes a body part, an attachment plate, a first adjustment part and a second adjustment part. The body part has an upper plate, a lower plate, and a sleeve disposed between the upper plate and the lower plate. The attachment plate has a connection hole therein and is jacketed outside the sleeve through the connection hole, and the first adjustment part is integrally connected to an inner wall of the connection hole of the attachment plate. The first adjustment part is capable of providing horizontal movement of the attachment plate relative to the body part. The second adjustment part is capable of providing vertical movement of the attachment plate relative to the body part.

A locking position stud fastener is configured to position, lock, and securely hold a lamp assembly to a vehicle body. A method for installing a lamp assembly on to a vehicle body having at least one opening for receiving a fastener includes the steps of securing a first end of a stud to the lamp assembly, rotating the stud about its axis, passing the stud through the vehicle body opening, and then locking and securing the stud in the vehicle body.

A positioning device with tolerance compensation including: a screw; a primary tightening member, and a secondary nut. The screw includes a driving portion cooperating with a driving tool to rotatably drive the screw and is located in an axial end portion of the screw; primary and secondary external threads, the primary external thread being further from the driving portion than the secondary external thread, the directions of the secondary external thread and the primary external thread are opposing; and an abutment projecting between the primary and secondary external threads. The primary tightening member includes a primary internal thread adapted to cooperate with the primary external thread, the primary tightening member and the abutment secured to an intermediate component. The secondary nut includes a secondary internal thread cooperating with the secondary external thread and is configured to bear against the intermediate component to fasten a first component on a second component.

The fastening device includes a nut (1) and a screw (2) coupled by being screwed together, the screw (2) being movable with respect to the nut (1), wherein the screw (2) comprises a head (3) provided with a washer (4) able to tilt in any adjustment direction, the axis of the washer (4) able to move within an angle by tilting with respect to the axis of the screw (2). A fastening method includes the steps of vertically introducing the fastening device in a polygonal hole until a seal (6) butts against the roof of the vehicle, and rotating the device in a counterclockwise direction until it butts against the same. The fastening device allows a function of adjustment to be carried out and compensates for the lack of parallelism and tolerance between the fastened accessory and the body of the vehicle.
