The present disclosure provides a tolerance compensation fastening assembly for fastening a first component to a second component which comprises a first compensation element and a second compensation element. The first compensation element comprises a first support portion which is provided with a first receiving hole that receives a shank of a fastener, and is connectable to the first component and movable relative to the first component in a longitudinal direction. The second compensation element comprises a second support portion which is provided with a second receiving hole that receives the shank of the fastener and is connectable to the first component and movable relative to the first component in at least one transverse direction perpendicular to the longitudinal direction. The first support portion and the second support portion are subjected to an axial fastening force applied by the fastener, and are at least partially made of metal.

Systems, methods, and devices are disclosed for securing structures. One fastener includes a threaded body and a head. The head includes a rounded axial protrusion having a first radial diameter, and a noncircular radial portion for securing the fastener. The noncircular radial portion has a second radial diameter greater than the first radial diameter. The noncircular radial portion is positioned between the threaded body and the rounded axial protrusion.

The present invention relates to a multi jackbolt tensioner and methods of using the same. The present invention alleviates some of the problems associated with presently available multi jackbolt tensioners.

A swivel nut assembly is configured to adaptively secure a first component to a second component. The swivel nut assembly includes a socket nut including a first portion having a first internal threading, and a second portion defining a swivel chamber. A swivel connector includes a ball having a first external threading. The swivel connector is moved into the swivel chamber via the first external threading threadably engaging the first internal threading to move the ball into the swivel chamber. The ball is rotationally captured within the swivel chamber after the ball is moved into the swivel chamber.

A compensation nut fastener assembly to connect first and second panels includes first and second nuts. The first nut includes a shaft having an outer threaded portion and a fastener-receiving channel. The first nut is connected to the first panel through the fastener, and the fastener is threadably secured to the first nut within the fastener-receiving channel. The second nut threadably retains the first nut, and includes a retaining wall having an internal threaded portion defining a central passage configured to threadably engage the outer threaded portion of the shaft of the first nut. The second nut is connected to the second panel, and the first nut is moveable within the central passage toward the first panel when the fastener threadably engages the first nut in order to compensate for a gap between the first panel and the second panel.

The present disclosure relates to a spring element for a device for compensating for tolerances between a first component and a second component, wherein the spring element comprises: at least two axial webs extending in the direction of a longitudinal center axis of the spring element and spaced apart from one another in the circumferential direction of the spring element, each of which, viewed in the direction of the longitudinal center axis of the spring element, has two opposite end sections connected by an intermediate section, wherein the end sections of an axial web have at least approximately the same radial distance from the longitudinal center axis of the spring element and the intermediate section arranged between these end sections has a different radial distance from the longitudinal center axis; and at least one connecting ring which connects the axial webs to one another.

A device for compensating for tolerances between two components to be connected to one another may have a fastening element for fastening to a first component provided with an opening and for connecting the component to a second component. The device may also have at least two axial tolerance compensation stages for compensating axial tolerances between the two components. The at least two axial tolerance compensation stages are each arranged between the fastening element and one of the components.

The present disclosure relates to a spring element for a device for compensating for tolerances between a first component and a second component, wherein the spring element comprises: at least two axial webs extending in the direction of a longitudinal center axis of the spring element and spaced apart from one another in the circumferential direction of the spring element, each of which, viewed in the direction of the longitudinal center axis of the spring element, has two opposite end sections connected by an intermediate section, wherein the end sections of an axial web have at least approximately the same radial distance from the longitudinal center axis of the spring element and the intermediate section arranged between these end sections has a different radial distance from the longitudinal center axis; and at least one connecting ring which connects the axial webs to one another.

A tolerance compensation device includes a base device having a tubular fastening portion that includes an internal, right-hand thread for receiving a screw-like fastening element. A tubular connecting portion, for connecting to a compensation structure, has an outer jacket wall that includes an external thread for connecting to a compensation structure, and a compensation structure having a flange-like setting element. An inner jacket wall of the setting element includes a threading configured to correspond to the external thread, and a socket-like anti-rotation element is disposed in a through-opening of the setting element, and an outer jacket wall of the anti-rotation element is connected to an inner jacket wall of the tubular connecting portion in a non-rotatable manner. The compensation structure is configured for presetting a distance in axial direction between the base device and a contact wall of the compensation structure extending orthogonally to the axial direction.

A fastening device, fixing an exhaust manifold (12) on a cylinder head (14) of an internal combustion engine, has a contact surface (20) supported relative to a cylinder head contact surface (22). A fastening edge area (16) has a wedge fastening flange area (24) with a fastening element support surface (26) inclined in relation to the contact surface (20) that has a wedge angle (W.sub.1). A fastening element (38) is pressed against the fastening element support surface (26) with a fastening flange support surface (40) with a fastening bolt unit (30) supported in relation to the cylinder head (14). The wedge angle (W.sub.1) and a coefficient of static friction (μ) of the frictional interaction of the fastening element (38) in relation to the exhaust manifold (12) is defined by: 0<W.sub.1<2 tan.sup.−1 (μ), in which W.sub.1 is the wedge angle, and μ if the coefficient of static friction.
