The invention relates to a floating, captive arrangement of a connection element on a component, in which the connection element extends along a longitudinal axis (LA) and has at least a head section and a shaft section, which adjoins along the longitudinal axis (LA) and is set back relative to the head section, in which the shaft section is passed, at least in sections, through a through-opening in the component and is connected, at least in the area of the free end of the shaft section opposing the head section, to a retaining plate element in such a way that the connection element is floatingly and captively arranged on the component, wherein the head section has first locking means and/or the retaining plate element has third locking means and the component has corresponding second locking means, wherein the first and/or third locking means interact with the second locking means in such a way that the connection element received, at least in sections, in the through-opening of the component is secured against at least section-wise twisting about the longitudinal axis (LA) relative to the component.

A facial alignment system that includes a first mask portion and a rear portion. The rear portion includes a tightening mechanism mounted thereon that includes first and second tightening members that extend from the rear portion to the mask portion. The first and second tightening members are configured to exert a tightening force on the first mask portion.

A deformable insertion fastening arrangement for insertion into a planar ply structure and for retention thereon by subsequent deformation, including a retention component having a passthrough opening passing through it along a passthrough axis and having a fastening configuration for fastening a further component thereonto; the retention component having at least two portions that are radially displaceable relative to the notional passthrough axis that passes centrally through the passthrough opening, the retention component, when considered in its undeformed initial state, is embodied segmentedly in a circumferential direction around the passthrough axis; at least two segments, constituting the radially displaceable portions, being connected to one another by at least one connecting configuration deformable in a circumferential direction; at least one segment being displaceable in a radial direction away from the passthrough axis against a shape inertia force of the at least one connecting configuration, accompanied by enlargement of the passthrough opening.

To improve fastening precision and economic feasibility, the present disclosure provides a clinching-type blind hybrid fastening apparatus inserted into and fastened to a frame part through which a first coupling hole is formed in a hollow shape and on one side of an upper surface thereof and a second coupling hole is formed on a lower surface thereof, the apparatus including a body part which is inserted into the frame part and has an outer lower surface rim seated on an upper surface rim of the second coupling hole, a blind fastening part including a rivet fastening portion that integrally extends upward from the body part and has an upper end disposed above the first coupling hole, a close contact step portion that is integrally formed at an upper portion of the rivet fastening portion, and a head portion that extends outward from an upper end of the close contact step portion, and a clinching fastening part that is integrally extending downward from the body part and has a lower end disposed below the second coupling hole.

A facial alignment system that includes a first mask portion and a rear portion. The rear portion includes a tightening mechanism mounted thereon that includes first and second tightening members that extend from the rear portion to the mask portion. The first and second tightening members are configured to exert a tightening force on the first mask portion.

A method of permanently attaching a fastener to a plastically deformable panel includes placing a fastener shearing edge in contact with a first surface of a panel and a die assembly in contact with an opposite second surface of the panel, and penetrating the fastener shearing edge through the panel to create a hole. The fastener shearing edge is driven into a swage formed as a recess in an end face of the die assembly to deform the fastener shearing edge outwards along the swage and into contact with the second surface of the panel. A bent portion of the panel is trapped between the deformed fastener shearing edge abutting the second surface of the panel and a tapered flange formed on an outer surface of the fastener that abuts the first surface of the panel. A die assembly and driving mechanism for attaching the fastener is also provided.

A fastener is staked to a sheet of equal or higher strength material. The fastener can be staked to a substantially circular shaped opening in the sheet material but other shapes of openings can be used. The opening is prepared by forming serrations in at least a part thereof. The serrations can take many forms and depths depending on the requirements for the particular application and materials being used. The serrations are formed by a doming tool and a punch tool aligned on opposite sides of the sheet material coming together to create the serrations. The nut is inserted into the serrated opening in the sheet material and force is applied to the fastener causing at least a portion of material of the fastener to flow at least partially into the serrations and secure the fastener to the sheet material.

A press-in nut is formed as a cap nut and has a nut body with a through hole, which is closed by a cap under formation of a blind hole. This is provided to obtain a media-tight connection with the nut body. The nut body has a ring collar at the top. In a pre-assembled state, the ring collar is only at least partially bent over, so that the cap is only held captively, without a media-tight connection being formed. The desired media-tight connection is only formed when press-fitting into a component.

An assembly part configured to be fastened to a counterpart includes a body traversed by a traversing hole and a fastening insert configured to receive a fastening device in a hollow of the fastening insert along a first direction to fasten the assembly part to the counterpart. The fastening insert has a proximal end portion and a distal end portion in the first direction. The fastening insert is positioned in the traversing hole. A movement of the fastening insert in a second direction opposite to the first direction is blocked by a first form fit between the distal end portion and the body, and a movement of the fastening insert in the first direction is blocked by a second form fit between the proximal end portion and the body.

Provided is a turbocharger, including: a compressor impeller (impeller) having a through hole; a shaft inserted through the through hole; and a fastening member caulked to a distal end portion of the shaft projecting from the through hole.
