A hydraulic fastener tool comprising with a piston in threaded connection with a single-unit puller that is inside a single-unit anvil. Inside the puller is a segmented collet assembly with an internal spring and guide tube. In use, the tool secures fasteners and ejects the severed fastener stem after fastening.

A setting head for a joining device, such as a press or a setting device, which setting head comprises the following features: a punch which is movable in a longitudinal direction such that a joining element can be joined into a component by means of a punch face arranged at a working end of the punch; a hollow cylindrical receiving sleeve which has a through-passage and which, with the punch in the through-passage, is guided adjacent to the working end of the punch concentrically and axially movably thereon; and two mutually opposite holding arms arranged on the receiving sleeve outside the through-passage each provide at least one laterally inwardly projecting holding end, with the result that the at least two holding ends allow the joining element to be releasably positionable adjacent to a punch-remote outlet opening of the through-passage and by the axially movable working end of the punch.

An upper drill tool including a central chuck, an upper component, a lower component and a coupling assembly. The central chuck has a chuck base and a chuck structurally configured to retain a drill bit. The upper component is attached to the central chuck and has a lower stop surface. The lower component has a central body and an outer ring that threadedly engages the central body, with the outer ring having an upper stop. The coupling assembly is configured to facilitate the slidable movement of the lower component from a first orientation wherein the upper stop is spaced apart from the lower stop surface and a second orientation wherein the upper stop is in abutting engagement with the lower stop surface, with the first orientation and the second orientation defining a stroke.

An automatic riveting gun and a method of operating same are disclosed, the automatic riveting gun includes a gun body including a rivet cavity, a front cavity, and a main cavity; a rivet clamping assembly is disposed on the gun body adjacent to the rivet cavity; a front-dynamic structure is movably disposed in the rivet cavity and the front cavity and a main-dynamic structure is movably disposed in the front cavity and the main cavity. The front-dynamic structure includes a claw sleeve. A claw mechanism is movably disposed in the main-dynamic structure. A front elastic element provides an elastic force to the claw mechanism and a main elastic element provides an elastic force to the main-dynamic structure.
