Fastener embodiments of the invention comprise 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.

A display system includes: a first upright oriented vertically; a second upright oriented vertically and offset horizontally from the first upright by a frame separation distance, the first upright and the second upright each having a plurality of openings therein and together defining a display opening therebetween; a first fastener attached to a display panel and inserted into one of the plurality of openings in the first upright; and a second fastener attached to the display panel and inserted into one of the plurality of openings in the second upright, each of the first fastener and the second fastener comprising a first portion and a second portion, the first portion having a first stud and a second stud, the second portion having an opening for receiving the first stud, the first stud configured to be inserted through a display panel and secured in the opening, the second stud configured to be inserted into one of the plurality of holes in the first upright or second upright, whereby the first and second fasteners hold the display panel in the display opening.

The present disclosure provides a lockable double shear dowel connector comprising two guide tubes, two dowels, two sleeves, an open end, and two orifices.

A connecting bolt has a bolt shank and a bolt head which has a radially outwardly projecting bolt projection. The bolt head has a latching projection between the bolt shank and the bolt projection on the side opposite the bolt projection.

A device for fastening a first object to a second object in a fastening direction is provided, the device comprising an anchoring element, a tension element and a prestressing element, wherein the anchoring element is provided to be anchored in a fastening direction in the second object, wherein the tension element is provided to transmit a tensile force from the anchoring element to the prestressing element to prestress the prestressing element in the fastening direction against the first object, and wherein the tension element comprises a composite of a plurality of fibers.

A toggle cam bolt is provided including a shank, a cam lever, a recess, and a toggle. The shank includes a first end and a second end. The cam lever is rotatably attached to the first end by a first pivot pin. The cam lever includes a lever handle and a cam lobe that is eccentric relative to the first pivot pin. The recess is located at the second end of the shank. The toggle is attached to the recess so that it is rotatable about a second pivot pin. A method of clamping two or more parts together using a toggle cam bolt is also provided.

An anchor for an anchoring with, for example, a synthetic resin mortar in an anchoring hole in an anchoring substrate made, for example, of stone, concrete or masonry. In order that a displacement of the anchor in the direction of a mouth of the hole and, as a result, potential failure of the anchoring can be ascertained at an early stage, a cap as position sensor holder having an electrical counter-contact, which cap is mounted on the anchor. If the anchor becomes displaced, the counter-contact moves out of contact with the anchor, with the result that the displacement can be ascertained.
