A fastener for attachment to a panel, having an inner skin and an outer skin, via a panel aperture in the outer skin. The fastener including an insert pillar, a base plate, a spring, and a top insert arranged and configured to allow longitudinal compression of the spring resulting in movement and deflection of components to promote ease of use, security, and durability.

A mounting assembly for use in mid-grab and/or edge-grab applications may include a clamp secured to a stanchion by a clamping fastener. The mounting assembly may also include a mounting plate which may be secured to a mounting device by the stanchion. The mounting assembly may be used, for example, to secure photovoltaic modules (or other devices or structures) of varying heights to a roof or other building surface.

A removable fastener for securing a first stud to a second stud each stud having an aperture with lateral and bottom edges, includes a joining member with a first end and second end having first and second notches sized to admit lateral edges made adjacent by placing the studs back-to-back. Fastener includes a locking member that has a stud end configured to rest on the bottom edges of the apertures and a fastener end configured to attach to the joining member, holding the joining member in position within the apertures when the joining member is engaged within the apertures; the fastener end may include a clip.

A fastener structure includes a head, a fastening portion and a twist break portion. The twist break portion is fastened at an object by the fastening portion, or is fastened at another object through the object by the fastening portion. Once the fastening portion is fastened, the twist break portion is twisted and broken. Thus, the fastener structure of the present disclosure is capable of providing a required object with a stable combining effect.

A fastener structure includes a fastener having a stem portion and at least one movement portion. The stem portion has a fastening section. The movement portion is formed on the stem portion and has a retaining section. With these arrangements, the retaining section of the movement portion can be detachably assembled to a first object and the fastening section can be then detachably assembled or fastened to a second object. In this way, at least two objects can be connected to and disconnected from one another in a quick and repeatable manner.

A captive screw, comprising: a screw; a press fit nut, to connect to an opening on a device and to accept a screw, including: a bottom portion, to extend through the opening; a top portion; and a middle portion, wherein the middle portion is smaller in circumference than the top portion and the bottom portion; and a sleeve including a protrusion, wherein the sleeve fits over the screw and attaches to the press fit nut via the protrusion.

A rotating structure includes a rotating part and a fixing piece. The rotating part has a lateral perforation part, the lateral perforation part is for perforating an object; the fixing piece is combined to the lateral perforation part and the object, so that the rotating part is movably combined with the object for making the rotating part rotate or move the object. Accordingly, the rotating structure of the present disclosure has the effects of simplicity of operation, saving labor and convenience.

An electrically driven fastener structure includes a body, a fastening unit and a wire. The body has a first assembly portion. The fastening unit has a second assembly portion corresponding to the first assembly portion. The wire is adapted to pass a current and to pass through the first assembly portion or the second portion to form a magnetic switch using the first assembly portion or the second assembly portion, so as to drive the magnetic switch based on on or off or strong or weak of the current, or to drive the magnetic switch based on on or off or strong or weak of a magnetic force.

Captive fastener systems and structural assemblies having captive fastener systems are described. The captive fastener systems include a captive fastener assembly having a sleeve and a captive fastener arranged within the sleeve, a mounting assembly having a bushing and a mounting fastener arranged to pass through the bushing, and a joining body having a mounting aperture, wherein the sleeve is attached to the joining body and the bushing and the mounting fastener are configured to pass through the mounting aperture. The mounting assembly is configured to provide a first degree of movement of the captive fastener system and the captive fastener assembly is configured to provide a second degree of movement of the captive fastener system.

A tolerance-compensating fastening arrangement for fastening a component to a structure includes a male fastener having a fastening bolt having a serrated outer profile; and a female fastener having a socket base arranged therewithin movable along a horizontal plane and having a conical funnel to receive the bolt such that horizontal tolerances between the male and female fasteners are compensable by movement of the socket base actuated through contact of the bolt with an inner surface of the funnel; and a socket jaw arranged on the socket base and having several jaw segments arranged circumferentially around a vertical axis to form a central jaw opening configured to receive the bolt through the funnel, the jaw segments configured movable radially with respect to the vertical axis to adjust a size of the jaw opening to retain the bolt along the vertical axis via contact of the serrated inner and outer profiles.
