A heat sink connector pin includes a pin assembly with linkage that provides the movement of a pin head or cap in a downward movement to cause multiple movable fingers at an opposing end of the pin to mechanically move from a retracted position that allows insertion of the heat sink connector pin through an opening in the substrate, such as a through-hole, to move to an outward extended position so that the multiple fingers engage or grasp a bottom surface of the substrate. In one example, the movable fingers are rotatably connected to share a same rotational axis with each other. In one example, the pin assembly includes a sleeve adapted to receive the shaft structure and is adapted to engage with the pin head. The sleeve includes a substrate stop surface adapted to contact a top surface of the substrate during insertion of the pin through the substrate.

A bolt for clamping adjoining parts includes a bolt body adapted for insertion in openings of the adjoining parts from one side of the adjoining parts. An actuator is received in the bolt body and actuatable from one end of the bolt body. Mounted in the bolt body and interacting with the actuator is a clamping mechanism which includes tilting elements configured to tilt out of the bolt body in opposition to a restoring force, when the actuator is actuated.

Fasteners and related systems according to the invention include a collet body having a first part of a two part anti-rotation arrangement and a cylinder body having a second part of the two part anti-rotation arrangement wherein the collet body and the cylinder body are matably axially translatable with respect to each other, and have the same or similar outer diameter in some embodiments or not in others. A threaded member rotationally engages the collet body and compressively contacts the cylinder body during operation of the fastener to creating a clamping effect. Rotational interference between the first and second parts of the anti-rotation arrangement preferably occurs at sectional face portions of at least the collet body. Resistance to induced rotation of the cylinder body relative to a work piece rotation of the threaded member is preferably provided by a tool engaging a tool interface present on the cylinder body.

A fastener for attaching a license plate to a vehicle includes a receiver having a shank portion and a head portion defining a recess, and an insert having a shank portion configured to be received within the recess defined by the head portion of the receiver and a head portion defining a recess for receiving a release mechanism within an interior of the shank portion and the head portion of the insert. The shank portion of the receiver is configured to secure the receiver to the vehicle. The shank portion of the insert is received within the recess defined by the head portion of the receiver with the license plate disposed between the head portion of the receiver and the head portion of the insert. A detent element of the release mechanism engages the head portion of the receiver to attach the license plate and the insert to the receiver and the vehicle. The release mechanism is depressed to release the detent element from the head portion of the receiver to remove the license plate and the insert from the receiver.

A positioning device including a plate having a first side and a second side opposite to the first side, a guiding pin mounted to the plate and extending perpendicularly from the first side of the plate, and an expandable pin mounted to the plate. An expandable portion of the expandable pin extends perpendicularly from the first side of the plate. The positioning device further includes at least two reflectors, and an identifier. The at least two reflectors and the identifier are not located on a common straight line. Furthermore, a method for mounting two structural parts to one another using such positioning device is provided.

A fastener is provided herein. The fastener includes, in one example, a block fixedly coupled to an interior spindle and mated with a slot in a threaded retaining spindle as well as a drive nut is threadingly engaged with the threaded retaining spindle and an unthreaded collet is coupled to the threaded retaining spindle. The fastener further includes a body that circumferentially surrounds the block and the threaded retaining spindle and the block, body, and threaded retaining spindle of the fastener are configured to axially translate in relation to one another and are substantially prevented from rotation in relation to one another, during different stages of fastener operation.

A temporary fastener a plunger having a distal portion including a plurality of plunger fingers, where depressing the plunger causes axial translation of a collet body to place the temporary fastener in an activated state where a plurality of flexible fingers in the collet body radially converge and where releasing the plunger places the temporary fastener in a clamped state in which the plurality of flexible fingers in the collet body are outwardly displaced. The temporary fastener further includes a web element positioned at a proximal end of a rod and including a plurality of opening permitting the plurality of plunger fingers to axially translate there through during depression and release of the plunger. The temporary fastener further includes a spring positioned within a case and exerting a restorative force on the collet body and the plunger in response to depression of the plunger.

A offset fastener includes socket including socket hole and bottom positioning portion affixed to first panel member, retaining shaft including shaft body axially movably positioned in socket hole and transversely movable relative to socket between center position and offset position, spring chamber transversely defined in shaft body, spring member mounted in spring chamber and floating ball supported on spring member and forced by spring member into abutment against an inside wall of socket that defines socket hole, positioning member axially extended from shaft body for inserting through positioning hole of second panel member when retaining shaft is disposed in center position and for locking retaining shaft to positioning hole when retaining shaft is moved to offset position, and stopper member fastened to retaining shaft and operable to move stopper member between center position and offset position.

A fastener system is provided that includes a spindle bolt having a threaded section and a tooling interface at a head, a bolt body at least partially mated with the spindle bolt, including an anti-rotation slot and an outer surface, a nut including an interior threaded portion and an anti-rotation extension, and an expandable ring mated with the nut and including a lower clamping surface. In a clamping configuration of the fastener system, the lower clamping surface extends beyond the outer surface of the bolt body, the interior threaded portion of the nut is threadingly engaged with the threaded section of the spindle bolt, and the anti-rotation extension mates with the anti-rotation slot. In an installation configuration of the fastener system, a diameter of the lower clamping surface is less than a diameter of the lower clamping surface in the clamping configuration.

The present invention provides a removable blind fastener (2) having a first tubular element (4) comprising an arm portion (22), a second tubular element (6) comprising an arm portion (28), and an elongate screw member (8). The elements (4 and 6) are arranged in telescoping relationship one with the other and which fastener (2), when in use as a temporary fastener, is caused to secure the component parts (10 and 12) of an airframe by causing telescoping movement of the elements (4 and 6) towards each other when the screw member (8) is turned in one direction and is caused to release the component parts (10 and 12) of the airframe by causing telescoping movement of the elements (4 and 6) away from each other when the screw member (8) is turned in an opposite direction. The arm portions (22, 28) of the elements (4 and 6) are located in mutual juxtaposition for telescoping movement upon rotation of the screw member (8) as aforesaid with end portions (30a and 32a) of elongate arms (30 and 32) of the arm portions (22 and 28) being brought into engagement with a tapered portion (44) of the screw member (8) whereby the arms (30 and 32) are caused to splay outwardly to bring the end portions (30a and 32a) into engagement with an underside (126) of the component (12) and moving the component (12) into secure temporary relationship with the component (10) of the airframe.
