The invention features the new system of spring compression to provide the force necessary to securely attach accessories to gear track systems. The invention also features a customized bolt design allowing the bolt to be inserted into the gear track system from near perpendicularly above, turned (rotated) such that the bolt flanges catch on the underside of the gear track flanges, and held into place via the compression spring(s). This allows the attachment/detachment of gear track accessories to take a significantly less amount of time versus the old method.

A fastener comprises a housing, a socket, a pintle and a locking feature. The housing includes a shaft, a central bore that extends axially at least partially through the housing and a ball lock aperture extending from the bore. The socket extends into the housing adjacent to the first end face, and is configured such that rotation of the first socket rotates the fastener. The pintle is positioned within the bore and includes an actuation end and a rod that extends axially from the actuation end. The rod includes a ball transitioning surface and a ball locking surface. The pintle is moveable axially within the bore between a designated lock position where the ball locking surface of the pintle is aligned in register with each ball lock aperture, and a designated unlocked position where the ball lock surface of the pintle is moved axially away from each ball lock aperture.

A retention apparatus, system and method of attaching items, panels or other devices to a rail formed in longitudinal lengths configured with a cross-sectional profile having multiple cooperating structures between the rail and a channel nut including a recess formed between a tooth and shelf on an interior first channel portion of the rail and a flange of the channel nut, between an anchor latch of the rail and hook flange on the channel nut, and cooperating forces and movement of the biasing element secured to the channel nut.

A releasable fastening device for boards, comprising an anchor configured for insertion between two adjacent boards and abutment with an underside of the boards. The releasable fastening device further comprises a rod in threaded connection with the anchor and a rotation element connected to the rod. The rotation element is configured for positioning on a topside of the boards and configured for being rotated by a user. The rotation element is configured for rotating the rod to thereby screw the anchor towards the rotation element.

A retention apparatus, system and method is useful for attaching items, panels or other devices to a rail formed in longitudinal lengths and configured with a cross-sectional profile having multiple cooperating structures between the rail and a channel nut including a recess formed between a tooth and shelf on an interior first channel portion of the rail and a flange of the channel nut, between an anchor latch of the rail and hook flange on the channel nut, and cooperating forces and movement of the biasing element secured to the channel nut.

A system and method for building a solid wall with a drop-in ceiling includes a floor track to be secured on a base floor. A support structure of studs is to be secured to the floor track. Cornice rails are to be placed on top of the studs. Splice plates are to connect ends of the cornice rails together. A top cladding is to be installed to at least a portion of the studs at a fixed distance below the top of the studs. The top cladding is to be installed prior to the cornice rails being secured to the top of the studs. Ceiling mounts are to be installed on top of the cladding in a manner that provides equal spacing reveals between the ceiling mounts and the cladding. Splice plates are to connect ends of the ceiling mounts together. A secondary cladding is to be installed to the studs. To complete the wall system, a drop-in ceiling is secured on top of the ceiling mounts.

A system to prevent a sliding nut in a channel in a bar from escaping from the channel, and to prevent the nut from entering a no-go-zone at the end of the channel. The system is adjustable to position the nut at a desirable location along the length of the channels to mount coupling devices onto the bar.

Installation system for a box profile (100) for a motor vehicle, wherein the installation system (1) has: —at least one carrier strip (10), which can be pushed into the box profile (100), —at least one nut element (20) for prepositioning on the carrier strip (10), wherein the nut element (20) is designed to be prepositioned in a releasable manner on the carrier strip (10), and the installation system (1) has a positioning strip (30), which can be displaced relative to the carrier strip (10) and is designed to arrange the at least one nut element (20), in the state in which the latter has been prepositioned on the carrier strip (10), on an opening (102) of the box profile (100). Installation method. Nut element.

A clamp bolt providing a bolt and two nut, each nut being screwed on an end of the bolt. The clamp bolt further including two washers, mounted around the bolt, and axially positioned between the two nuts.

An apparatus for assembling screws, the apparatus includes a rack and a holder. The holder is arranged on the rack. The holder includes a convex and an opening. The opening is communicated with the convex, the screw is capable of moving in the opening and latched to and fasten to the convex.
