An apparatus for threading a tool unit onto an elongate structural element. The apparatus has a holding arrangement for holding it on a feed device, a tool unit to be threaded onto the elongate structural element. The tool unit has a tool axis and a vibration unit connected to the tool unit and configured to generate a periodic force in at least one first spatial direction that runs transversely with respect to the tool axis. First and second coupling components, held elastically on one another, are provided. The first coupling component is connected to the holding arrangement, the second coupling component is connected to the tool unit. The vibration unit is operated, during a feed movement of the holding arrangement for threading the tool unit onto the elongate structural element, to add an additional, periodically varying transverse component to a feed force acting on the tool unit.

A representative fastening tool which fastens a work piece by utilizing a fastener that includes a pin in which a shaft portion and a head portion are integrally formed and a hollow shaped collar which is engageable to the pin, wherein the work piece is disposed between the head portion and the collar. The fastening tool includes a pin holding portion which can hold an end part region of the shaft portion, wherein the fastener is fastened in a state that the collar and the head portion clamp the work piece and the end part region is integral with the shaft portion, wherein the controller has the pin holding portion move in the first direction to conduct the fastening of the fastener by a motor drive control mode defined as a drive control of the motor based on motor drive current and motor drive electric power.

A fastening tool includes a bolt-gripping part, an anvil, a bolt-gripping-part driving mechanism, a motor, a housing, and thrust rolling bearings. The bolt-gripping-part driving mechanism includes a first mechanism part supported by the housing and a second mechanism part connected to the bolt-gripping part. The second mechanism part is configured to be driven in a longitudinal-axis direction by the first mechanism part being rotationally driven, so that the bolt-gripping part is moved in the longitudinal-axis direction relative to the anvil. The thrust rolling bearings are disposed on a first direction side and a second direction side of the first mechanism part, respectively.

Techniques for implementing and/or deploying a swage machine, which includes a die plate that enables a die to be used to conformally deform a pipe fitting around pipe segment tubing to be loaded in the swage machine, a grab plate having grab plate sections that are pivotably connected, and grab adapter sections. Each grab adapter sections includes a base sub-section connected to a corresponding grab plate section, in which an inner surface of the base sub-section includes an alignment notch, and a modular sub-section to be secured to the base sub-section, in which an outer surface of the modular sub-section includes an alignment tab to be disposed within the alignment notch in the base sub-section and an inner surface of the modular sub-section includes a grab tab section that matingly interlocks with a fitting grab notch on the pipe fitting to facilitate securing the swage machine to the pipe fitting.

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.

Two piece tack rivets and method of forming holes for permanent fasteners. The tack rivets have a stem with a head on one end and a grooved region adjacent the other end, and a locking collar for fitting over the grooved region of the stem for deforming into the grooved region of the stem on applying a setting force between the locking collar and the stem. The head includes cutouts formed therein. The cutouts prevent the head from forming large chips or strips when drilled.

Systems and methods are provided for inspecting installation of a fastener. One method includes monitoring hydraulic pressure of a tool that is installing the fastener, detecting that the hydraulic pressure has dropped by more than a threshold amount within a period of time, determining that a pintail of the fastener has snapped in response to the detecting, and reducing the hydraulic pressure in response to the determining.
