The invention concerns a family of insertable temporary fasteners (100) comprising the following: a body (101) with a bearing face (102) at least one clip (103) with a hooking spur (104) a threaded rod (105, 205) connected to the clip, with a control nut (107, 207) screwed onto the said rod The family comprises at least two temporary fasteners (100) with different diameters and nuts with different lengths (116). The invention also concerns a set comprising such a family of fasteners, along with an installation device (13) comprising a means (26, 30) of detecting the length of the nut. The invention enables the installation device to automatically determine the appropriate tightening torque when installing the fastener based on the length of the nut.

A locating pin for positioning one or more workpieces on a mounting member is provided. The locating pin includes at least one cam being radially moveable between an extended position and a retracted position. The at least one cam engages the workpiece while in the extended position to hold the workpiece in place. The at least one cam is spaced from the workpiece while in the retracted position to allow the workpiece to be positioned on, or removed from the locating pin.

A temporary fastening device comprises a collet and mandrel connected to a temporary fastener body. The device comprises a first float cap, a second float cap, a third float cap, and a temporary fastener body which may be axially connected. The lateral clearance between the collet and a first aperture defines a first radially extending float region. The lateral clearance between the second float cap and the first float cap define a second radially extending float region. The collet and temporary fastener body may radially translate within the first and second radially extending float regions.

The invention relates to a fastener (10) for the temporary assembly of at least two pre-drilled structures of the type comprising: a body (11) able to come into contact with a face of the structures to be assembled; a spacer (17), secured to said body; two elastic half-clips (15), each clip having a hooking spur (16); a mechanism that can be moved relative to the body, comprising a threaded rod (18) connected to the half-clips, and a control nut (20) mounted on said rod, the control nut comprising: an internal tapping (19) cooperating with the thread (25) of the rod; an external thread (26) cooperating with an internal tapping (28) of the body; the body thread and the control nut thread being opposite handed.

A marking apparatus facilitates blind slide-mounting of an object to a mounting surface in a desired alignment using the object as an alignment template. A retention element in receipt of a post is movable against resilient bias to allow the head of the apparatus to capture a mounting slot in the object. The resilient bias moves the retention element to a gripping position, and a cover is rotated to cause a tightening element to secure the grip of the apparatus to the object. A rotational detent element offset from the head prevents the post from rotating with respect to the retention element. When affixed to the object, the apparatus is used to mark the appropriate location for installation of a fastener to supportingly engage the slide-mount slot of the object. The apparatus may include an orthogonality adapter to ensure that it remains orthogonal to the object during certain marking operations.

The present disclosure illustrates a fastening device. In the fastening device, a sleeve is formed with a through-hole which defines a rotation space, a position-limiting ring is formed on the sleeve and includes a first position-limiting fastening groove and two second position-limiting fastening grooves; a fastening member is formed on a bottom surface of a rod head of a rotary knob device dispose outside the sleeve; a long protrusion rod and two short protrusion rods are formed in the sliding inner hole of the assembly space and respectively aligned with the first position-limiting fastening groove and the two second position-limiting fastening grooves. During locking operation, the drive cap can be bi-directionally rotated; and during unlocking operation, the drive cap can only be unidirectionally rotate, thereby achieving the purpose of easily recognize the locked or unlocked state according to different hand feeling in 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.

The present invention is concerned with improvements to removable fasteners and particularly relates to removable and re-usable fasteners with features that allow them to be gripped and handled positively. The present invention therefore provides a fastening system comprising a fastener and a tool, the tool being suitable for installing and removing the fastener from an aperture in a work-piece, wherein the fastener has a main body and a head at one end, and wherein the head of the fastener and the tool have grip features that allow the fastener to be releasably locked to the tool to prevent separation of the fastener and tool during installation and removal of the fastener. This allows the fastener to be handled positively without fear of the fastener becoming misaligned, or dropping off the tool.

A method is provided for assembling an apparatus. During this method, a circuit element is arranged with a circuit board. The circuit element includes an element aperture. The circuit board includes a board aperture. A plunger is moved in a first direction to pass a distal end of the plunger through the element aperture and the board aperture and into a volume adjacent the circuit board. A retainer is pivoted within the volume. The retainer is pivotally mounted to the plunger at the distal end of the plunger. The plunger is moved in a second direction to clamp the circuit board between the retainer and the circuit element.
