A pipe or tube hanger consisting of a loop clamp combined with a blind rivet fastener which has the joint deformed to stiffen the blind rivet so it may be used as a tension member in the application. This will replace cast iron parts which have been typically used for this application. See FIG. 1. Because of air pollution many small cast iron foundries no longer operate in the United States. This novel methodology also eliminates weld joining of the two parts which requires post plating to restore cladding or galvanizing or post painting of the parts. Using this mechanical joint enables the use of pre-painted or galvanized material and allows fully finished parts to exit the automated fabricating process and go directly into shipping containers dramatically reducing handling and reducing the customers costs and making domestic manufacturing of the product competitively possible.

A press-fit connection between a high-strength component and a press-fit element is characterized by a non-circular previously made hole into which the press-fit element having a collar is inserted. Here, the collar is merely upset and pressed against a hole rim without embracing an underside of the component. Preferably, the hole rim is widened in a longitudinal direction such that a form-locking connection acting in opposition to the longitudinal direction is formed. The non-circular hole geometry is produced with the aid of a punch of circular cross sectional geometry, in that a cutter of the punch has leading and recessed cutting regions, with the result that disrupted partial regions are formed.

A method of connecting a first component and a second component with the aid of an auxiliary joining part, wherein the auxiliary joining part is formed from a pin and a plate. A position of intended fracture is present between the plate and the pin. The first component, the second component and the auxiliary joining part are brought into a stacked arrangement such that the plate contacts the first component and the pin projects away from the side of the plate remote from the first component. A force is exerted on the pin of the auxiliary joining part in the direction towards the stacked components which leads to a fracture at a position of intended fracture and the pin is used in order to pierce slugs from the stacked components. The end of the pin which is pressed through the second component, and/or a washer which is optionally provided there, is deformed in order to provide a form-locked connection to the second component or to a washer which is provided there. Furthermore, an auxiliary joining part is claimed.

The invention relates to a device for fixing an electrical connection terminal to a support having an opening extending between opposed front and rear faces, the device comprising: a bush for location within the opening of the support and provided with opposed front and rear ends between which extends a through-hole, the bush having a first deformation region configured for lateral expansion; a dowel configured for forced insertion into the through-hole so as to cause deformation of the bush, the dowel being provided with connection means engageable with a connector to facilitate the forced insertion of the dowel into the bush and to facilitate fastening of a terminal to the support; characterised in that the bush includes a second deformation region configured for axial contraction and lateral expansion upon forced insertion of the dowel in the bush.

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.

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.

The invention relates to a fastening element for fastening to a workpiece, said fastening element comprising at least a first workpiece element having a first opening and a second workpiece element having a second opening aligned with the first opening, wherein the fastening element has a first contact section having a first contact surface for contact with a region of the first workpiece element surrounding the first opening and a second contact section having a second contact surface for contact with a region of the second workpiece element surrounding the second opening, with the first contact section and the second contact section being connected to one another by means of a reshaping section, and with a rivet section extending from the second contact section in a direction facing away from the reshaping section. The invention further relates to a corresponding component assembly and to a method of manufacturing such a component assembly.

A coupling bolt or pin, in particular a ball pin, with a coupling head, such as a ball head, and a thread shaft. The thread shaft comprises a thread in a longitudinal portion of the thread shaft, which extends parallel to a central longitudinal axis of the thread shaft. Within the longitudinal portion of the thread a thread inhibition is provided by means of which a frictional connection between the thread and a counter thread engaging therein and being present at a radial inner wall of a thread opening is increasable. A disc-shaped support structure is provided between the coupling pin and the thread, a radial extension of which is adaptable to a diameter of the thread opening so that the coupling pin is supportable against a lateral load with respect to the axis of the coupling pin within the thread opening.

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.
