The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position and a drawing mandrel which is able to be brought releasably into operative connection with the drive piston and is able to be adjusted by the drive piston between a rivet receiving position and a setting position. In order to provide a riveting tool of the type mentioned in the introduction, uniform setting processes of rivets being able to be carried out thereby with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position of the drawing mandrel comprises a setting unit comprising a stroke limiting element which is able to be adjusted in the longitudinal axial direction of the drive piston and which is able to be brought into engagement with the drive piston.

The present invention is an electrical box cover system and method of installation that covers and protects existing electrical boxes and their electrical components. This invention prevents corrosion and the resulting damage to the mechanical and electrical components of the electrical box while ensuring the electrical box is safe to open and allowing access to the inside of the electrical box. The electrical box cover system includes a cover, fasteners, and a gasket. Generally, to install the cover, the fasteners are drilled through the cover and onto the sides of the damaged electrical box with the gasket, which is placed in the cover.

A method for configuring a hand-held riveting tool operated by an electric drive to set a blind rivet element in a setting operation. The hand-held riveting tool includes a mandrel configured to perform an axial movement so as to perform the setting operation of the blind rivet element, and a control unit which monitors the axial movement of the mandrel. The mandrel includes a front end position to which the blind rivet element is fitted in a form-locked manner and/or a force-locked manner. The method includes axially moving the mandrel from the front end position into a rear end position which is assumed at a beginning of the setting operation, and automatically adjusting the rear end position of the mandrel based on a parameter provided to the control unit.

A two-piece, one-sided-installation fastener system may have an internally-threaded sleeve having a shank and a sleeve head. The fastener system may include an externally-threaded core bolt having a frangible driving provision and a core bolt head.

A method for setting up a riveter comprising an electrical drive which is configured to place a blind riveting element in a location hole. The riveter applies a tensile force to a tensile element of the blind riveting element during a rivet placement process so that the tensile element tears away from a remainder of the blind riveting element at a predetermined breaking point at an end of the placement process. The tensile force used to place the blind riveting element is defined by an adjustable maximum value which is determined during the setting up. The method includes performing the placement process with the blind riveting element of the type to be used, acquiring a progression of the tensile force during the placement process, determining at least one characteristic value from the progression, and fixing the adjustable maximum value as a function comprising the at least one characteristic value.

A blind rivet element for fastening to a workpiece which has a hole, which is in particular preshaped, comprises a sleeve body and a bolt element led through the sleeve body, wherein the blind rivet element can be introduced into the hole of the workpiece and the sleeve body can be sectionally deformed by an axial movement of the bolt element relative to the sleeve body to fasten the blind rivet element to the workpiece. The sleeve body has at least one contact section which is arranged and configured such that the contact section cuts into a wall of the hole and/or into a region around the hole and/or effects a deformation of the wall of the hole and/or of the region around the hole, in particular to establish an electrical contract between the workpiece and the blind rivet element.

A tacking fastener for securing workpieces together to form a temporary assembly is provided that includes a stem and a sleeve. The stem includes a proximal end portion, a central portion, and a distal end portion. The stem further includes a head disposed at the proximal end portion, the head defining a distal face having a gripping feature. The sleeve includes a flange disposed at the distal end portion, the flange defining a proximal face having a gripping feature. The sleeve is disposed around the stem and configured to form a tacking rivet upon installation of the tacking fastener. The sleeve is plastically deformed during installation to form a plurality of bulbs, thereby being capable of securing workpieces of varying grip length. The stem and the tacking rivet remain within the workpieces after the workpieces are secured.

The present invention discloses a nut riveter comprising a front riveter seat with a cavity, a rear riveter seat arranged in the cavity of the front riveter seat and located at a rear end of the front riveter seat, a nut adjusting mechanism arranged at a front end of the front riveter seat, a nut riveting rod installed in the nut adjusting mechanism, wherein two sides of the rear riveter seat are each connected to a handle through a connecting rod; a pull rod seat located in the cavity of the front riveter seat, wherein a pull rod is inserted into the pull rod seat, wherein a rear end of the pull rod is connected with a pull rod retractable mechanism.

A fastener installation tool includes a nose assembly, first and second cylinders, first and second pistons, and a yoke. The nose assembly is adapted to apply an axial load to a fastener along a longitudinal axis of the nose assembly. The first and second cylinders are diametrically opposed to one another with respect to the longitudinal axis of the nose assembly. The first piston is disposed within the first cylinder and is movable along a longitudinal axis thereof. The second piston is disposed within the second cylinder and is movable along a longitudinal axis thereof. The yoke connects the first piston, the second piston, and the nose assembly such that motion of one of the pistons along its corresponding longitudinal axis causes motion of the other one of the pistons along its corresponding longitudinal axis and motion of at least a portion of the nose assembly along its longitudinal axis.
