The invention relates to a pull-out tester () for a setting tool used for setting a setting bolt (), comprising a retaining part () for holding the setting bolt (), an elastic element (), at least one means () for transmitting a pull-out force acting on the setting bolt () onto the elastic element () such that if a pull-out testing force acting on the setting bolt () is exceeded, the connection between the setting bolt () and the pull-out tester () can be detached due to a deformation of the elastic element (). The problem addressed by the invention is that of being able to provide a substantially constant pull-out testing force, even in different temperatures and with a different pull-out speed of the pull-out tester (). The problem is solved in that the force transmitted to the elastic element () in order to deform the elastic element () substantially causes an elastic deformation of the elastic element () and the connection between the setting bolt () and the pull-out tester () can be detached due to the substantially elastic deformation of the elastic element ().

Pull-out tester for a setting tool

A fastening system for fastening an add-on part on a setting object comprises a setting bolt having a first end and a second end, comprising a fastening section and a load application section, a sealing element with an opening for sealing the setting bolt inserted into the setting object when the setting bolt is arranged within the opening, and the add-on part being fastened on the load application section of the setting bolt.

Fastening system

A nail-shaped fastening element having a shank, at whose one end a tip is configured and at whose opposite other end a head is configured, and having a sleeve-shaped washer is disclosed. At a first end facing the tip, the sleeve-shaped washer has a first collar that narrows the opening cross section of the sleeve-shaped washer and, at a second end facing opposite the first end, it has a second circumferentially outwardly disposed collar.

Fastening method using a nail-shaped fastening element

A threaded bolt includes a head (), a load cation section () having a bar-shaped core region (), an attachment section (), with the head (), the core region (), and the attachment section () being formed as a one-piece part formed of metal, and a thread ()-carrying threaded sleeve () formed of a plastic material and secured radially outwardly on the core region (), with the thread () of the threaded sleeve () forming the outer thread of the load-application section ().

Threaded bolt

A combustion-engined setting tool for driving fastening elements such as, e.g., nails, bolts, or pins in a workpiece, includes a plate-shaped member () axially displaceable in the tool combustion chamber (), a member () for displacing the plate-shaped member (), a holding device () for retaining the plate-shaped member () at an axial end () of the combustion chamber () against action of the displacing member (), with the holding device () having magnetic elements () for producing a holding force for retaining the plate-shaped member () and a device for overpowering the holding force produced by the magnetic elements ().

Combustion-engined setting tool

A combustion-engined setting tool for driving fastening elements in a constructional component includes a guide cylinder (), adjoining the combustion chamber () and in which a setting piston () is displaceable, a press-on element (), and a transmission device for connecting the press-on element () with the combustion chamber rear wall () for axially displacing same in response to a press-on stroke of the press-on element, with the transmission device being formed as a cable drive () having a transmission member () and at least one deflection roller () for the transmission member ().

A setting device () drives fastening elements into a receiving material and includes a housing () with a piston guide () arranged in the housing () and with a hollow space () in which a setting piston () is displaceably mounted. A bolt guide () is connected to the piston guide () by an interface (). The setting device further has a piston restoring device () with an adjusting member () which engages in the piston guide () in a work position and is moved out of the piston guide () into a release position (). Further, there is a securing element (), with the adjusting member () being held in the work position () in a first position () of the securing element () and the adjusting member () being released to move into the release position () in the second position () of the securing element ().

Setting device

An explosion power-operated setting tool includes a setting piston () for driving in fastening elements in constructional components, and a resetting device () having a lever-shaped resetting member () for returning the setting piston () from its end position () into its initial position (), a bearing section () for supporting the lever-shaped resetting member (), and a damping member () for damping the lever-shaped resetting member () upon the resetting member () impacting the bearing section (), with the damping member () having a bearing surface () which the rear surface () of the lever-shaped resetting member () abuts and which has a profile substantially corresponding to a profile of the rear surface () of the lever-shaped resetting member ().

Explosion power-operated setting tool

An explosion-power operated setting tool for driving fastening elements in a structural component includes a setting piston () displaceably arranged in the guide chamber () of a piston guide () arranged, at least partially, in the tool housing (), a resetting device () having a resetting member () for returning the setting piston () in its initial position () after completion of a setting process, and a spring () for resiliently biasing the resetting member () in a direction of its initial position, and a damping device () for the spring ().

A setting tool for driving fastening elements includes a piston device () for the setting piston () and arranged in a setting direction end region of the hollow chamber () of the piston guide (), with the piston stop device () having a stop member () adjoining the hollow chamber () in the setting direction and including a leadthrough () having an inner conical active surface () that cooperates with the conical active surface () of the setting piston (), and with at least one of the active conical surface () and the active conical surface () being provided with a friction-reducing coating ().

Setting tool

The invention relates to a combustion-driven setting tool for fastening elements having a housing (), a piston guiding cylinder (), which is displaceably mounted in the unit housing in the cylinder longitudinal direction, a piston () guided in the piston guiding cylinder () for driving a fastening element () into a receiving material (), a receiving assembly () situated coaxial to the piston guiding cylinder () for the fastening element (), as seen in the driving direction, lies in front of the piston guiding cylinder () and is displaceable relative to same; an elastic adjusting assembly (), which constantly tends to separate receiving assembly () and the piston guiding cylinder () from each other; and a piston mounting (), which is attached to the on the end of the receiving assembly () facing towards the piston guiding cylinder ().
