A fastener with a freely translatable collet body, which at least partially translates within an auxiliary structure, and further comprise a captive threaded screw for rotationally engaging with the collet body to transform rotational movement into translational movement through substantial arresting of collet body rotation by way of an anti-rotation means. The screw comprises a free-spin feature that functionally, but not physically, decouples a drive tool from the collet body.

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 mateably 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 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.

A fastener including a screw configured to threadingly engage a drive sleeve and method for fastener operation. The fastener, in one example, further includes a collet body with legs that extend from a crown, where each of the legs includes a clamping foot that extends therefrom and wherein each of the clamping feet mate with a sleeve opening in the drive sleeve. The fastener further includes a housing that mates with the drive sleeve such that rotation of the drive sleeve is prevented and vertical translation is permitted.

A fastener is provided. The fastener includes a housing with a housing opening and a collet body at least partially enclosed within the housing, the collet body includes a crown having a crown opening with a threaded section and a leg that extends from the crown and including a foot. The fastener further includes a screw with a head positioned in the housing opening, an upper threaded section, and a lower unthreaded section, where the housing opening and the crown include a set of splined protrusions and a set of splined recesses mated with one another, where the sets of splined protrusions and recesses include ramps and are designed to permit the collet body and the screw to transition into a free-spin configuration, and where a spring is designed to exert a return force on the collet body or the screw when the fastener is in the free-spin configuration.

A reusable blind fastener including a bushing, a nut, a tail, a receiver, an expansion device, and a screw. The expansion device having an exterior surface that is discontinuous and configured for selective elastic deformation when engaging a portion of the screw.

A pin clamp for the temporary assembly of perforated structural parts, includes a main tubular body extending along a longitudinal axis X and a bearing face intended contact first face of the structural parts, a clip able to pass through opposite perforations, in said parts, the clip being translationally movable along the longitudinal axis, driven by the rotation, about said axis, of a tie rod having a tapped bore engaging a threaded end of the clip, the clip comprising branches, each ending with a catching spur for contacting with a final face of the structural parts, the branches being radially and progressively separable along a separator, placed between the branches and is-fixed relative to the main body, under the effect of the recoil of the clip, the separator comprising a transverse part introduced into a longitudinal groove of the clip and rotationally blocked in a groove provided in an element that is fixed relative to the main body.

A ball-lock type fastening device for connecting a work piece to a structure is disclosed. The fastening device includes a number of features designed to improve the reliability, repeatability and strength of the locking mechanism compared to traditional ball-lock fasteners. The features include the shape of the locking balls, the shape of the retention housing which engages the locking balls, and mechanisms for controlling deployment and retraction of the locking balls.

The present disclosure illustrates a fastening device including a sleeve, a rotary knob device and a drive cap. The sleeve is formed with a through-hole which defines a rotation space at a side thereof. A fastening part and a position-limiting ring are formed on an outer side of the sleeve, and the position-limiting ring includes multiple position-limiting fastening grooves on a periphery thereof. The rotary knob device includes a rotary rod movably inserted through the through-hole. The assembly space of the sleeve is formed with a sliding inner hole for covering the position-limiting ring of the sleeve, and the position-limiting ring is longitudinally movable in the sliding inner hole, and the sliding inner hole includes two long protrusion rods and two short protrusion rods formed on the sidewall thereof and separately fastened in the position-limiting fastening grooves. Therefore, the fastening device can be operated for locking or unlocking easily.

A method and temporary fastener for substantially simultaneously clamping a drill jig and a plurality of layers. The temporary fastener may comprise a first system and a second system. The first system may be configured to secure the temporary fastener to a drill jig. The second system may be configured to secure the temporary fastener to a plurality of layers of material beneath the drill jig.
