A fastening system including such a fastening apparatus, as well as to a method for fastening a first vehicle component to a second vehicle component by way of a bolt.

The present invention relates to an assembly of a first component (1) and a second component (2) of a wind turbine, the assembly comprises, a paired eccentric cam adjuster (10) adapted for a connection of the first component and the second component of a wind turbine, said components (1,2) each having at least one hole (3,4), the adjuster comprising, a first and second eccentric cam adjuster (7,8), both comprising, a tube (101) with an outer surface and an inner bore (103), with a first central longitudinal axis (321) of the outer surface having an offset (320) from a second central longitudinal axis (322) of the inner bore and a flange (102) arranged at one end of the tube, said cam adjusters (7,8) arranged to be inserted into said holes, and a bolt (5) and a nut (6) arranged to be inserted in the inner bores.

A buoyant fastener structure includes a body portion and a fastening element. The body portion has a rotation-preventing portion and a position-limiting portion. The fastening element has a position-corresponding rotation-preventing portion, a position-corresponding position-limiting portion and a fastening portion. The rotation-preventing portion and the position-corresponding rotation-preventing portion prevent each other from rotating. A rotation-preventing buoyancy level exists between the rotation-preventing portion and the position-corresponding rotation-preventing portion. The position-limiting portion corresponds in position to and limits the position of the position-corresponding position-limiting portion. Therefore, the body portion is coupled to a first object, whereas the fastening portion is coupled to or removed from a second object, so as for the first and second objects to be coupled together and separated, repeatedly and quickly. Furthermore, the second object coupled to the first object is movable on the fastening element to adjust the position of the second object.

Disclosed are fastening systems for coupling a first component to stud, shaft, or the like via a sleeve assembly. The fastening system comprising an upper sleeve component, a lower sleeve component, and a nut. The upper sleeve component defines an upper sleeve opening, while the lower sleeve component defines a lower sleeve opening. The lower sleeve component comprises one or more flexible tabs configured to engage the upper sleeve component via the component opening. The nut is configured to pass through a sleeve opening to engage the stud. The sleeve opening is defined by the upper sleeve opening and the lower sleeve opening.

A tie rod for spanning a duct interior to join duct walls bounding the duct interior, that can be simply and inexpensively fabricated from sheet metal or other suitable material, including automatically, securely fastenable quickly and easily to the duct walls, often by one person, and which can be configured to be nestable for efficient storage and shipping, of elongate construction for spanning a duct interior, with a transverse attachment flange or flanges that can be pre-bent or bent onsite at the installation location via special bending features to snug to a duct wall, and include holes for threadedly receiving fasteners, having a shape and size to reduce fastening torque, with a two attachment flange configuration that resiliently self retains the fastener against loosening from vibration and other forces.

The present invention relates to a fastening device for fastening a first component to a second component, where the fastening device includes a spacer element which is configured for positioning the first component so as to be spaced apart from the second component in a first axis (Y) and for fixing the first component so as to be spaced apart from the second component, where the spacer element includes a stop surface which is used for supporting the fastening device on the second component, where the spacer element is integrally-formed, and a tolerance element which is configured for movably receiving the spacer element in the first direction (Y) and for compensating tolerances between the first component and the second component in a second axis (X) and in a third axis (Z), where the tolerance element is integrally-formed.

In accordance with one or more embodiments of the invention, nut restrainers and methods of use are presented, particularly as they apply to high-strength bolted connections for steel structures. Nut restrainers may define a cavity that accepts insertion of a nut, and may include deformable or removable centering elements that allow the nut to move laterally to accept a bolt that is inserted non-concentrically with the nut restrainer, and may comprise a mobile central portion and a rigid outer portion; A method of positioning a nut restrainer concentric with a bolt hole accurate to within the radial tolerance of the bolt hole.

A dual-sleeve, locking adjustment arrangement includes a position-sensitive component comprising an aperture, an outer eccentric sleeve disposed in the aperture, and an inner eccentric sleeve disposed in the outer sleeve. Rotation of the outer sleeve with respect to the position-sensitive component and the inner sleeve drives rotation of the position-sensitive component to adjust an angular position of the component.

A fastener having a cylindrical shank with a fastener head attached to the first shank end, the head having a tool slot for engaging a tool, the tool slot directed away from the first shank end and a lower head surface adjacent the shaft. The cylindrical shank has a head collar adjacent the head, a threaded collar having securing threads, the threaded collar disposed along a portion of the second shank end, a shank smooth portion disposed between head collar and the threaded collar and a grip washer disposed along the collar. The grip washer has a first washer side with a plurality of protrusions and a second washer side having a profile corresponding with the lower head surface, wherein the grip washer is rotatable about the collar and the lower head surface. The fastener includes a retractable frame rotatable about the shank smooth portion.

The subject matter relates to a tolerance compensation comprising a flat part with a first recess for receiving a bolt of an attachment part and a tolerance slider with a second recess for receiving the bolt.
