A fastening tool system includes a housing including a main body having a proximal end and a distal end. The main body defines an internal chamber extending between a proximal opening at the proximal end and a distal opening at the distal end. A plunger includes a stem that extends into the internal chamber through the proximal opening. The plunger is configured to be moved in relation to the main body between a retracted position and an extended position. A securing stud is in a collapsed position when the plunger is in the retracted position. The plunger is configured to move into the extended position to engage the securing stud to expand the securing stud into an expanded position.

The present invention provides a threaded connecting member and a threaded connecting structure with a radiating function. Since a radiating passage which extends along a length direction of the threaded connecting member is provided on the threaded connecting member and the radiating passage runs through one end of the threaded connecting member to the other end of the threaded connecting member, when the threaded connecting member with the radiating function provided by the present invention is used, the threaded connecting member is provided in a connecting hole in a connector in a penetrating manner, the radiating passage communicates spaces on two sides of the connector, gas in the spaces on the two sides of the connector can perform heat exchange through the radiating passage and thereby the heat diffusion capability of a connected device is improved.

A work apparatus includes a housing part and a stud bolt for fastening a work tool on the housing part. The stud bolt extends along an axial direction and has a first section and a second section in the axial direction. The first section is at least in part arranged in a receptacle of the housing part. The second section protrudes from the housing part in the axial direction. The first section of the stud bolt in a first lower portion thereof has an outer thread which, for transmitting longitudinal forces (L), threadably engages an inner thread of the receptacle to define a threaded connection. The first section for transmitting transverse forces (Q) to the housing part, in a second lower portion thereof, has a support region supported on the receptacle. The support region is disposed at a spacing (a1) from the threaded connection.

Threaded pin made of a starting material, wherein the threaded pin comprises a base, a tip portion, which is spaced apart from the base in the direction of a longitudinal axis of the threaded pin, wherein the tip portion comprises a bridge portion, and a first side wall with an outer profile, said first side wall extending from the bridge portion to a first base part, and a second side wall with an outer profile, said second side wall extending from the bridge portion to a second base part, wherein the first side wall is formed from a different part of the starting material to the second side wall and the first base part is formed from a different part of the starting material to the second base part, wherein part of the first part is in engagement with part of the second base part, and/or part of the first base part is connected to part of the second base part, wherein, as an alternative or in addition, part of the first side wall is in engagement with part of the second side wall, and/or, in addition, part of the first side wall is connected to part of the second side wall.

A filter element assembly comprises a filtration media and an end fitting through which a sealing connection is made between the assembly and a housing so that the end fitting defines a flow path between the housing and the filtration media. The end fitting has first and second parts which can be separated axially, and the filter media extends axially away from the second part in a direction away from the first part. Each of the parts has an outer wall with an external threaded cylindrical surface, and each of the first and second parts has an axially facing edge surface which faces the other of the first and second parts, the facing edge surfaces shaped to define a pre-determined relative rotational alignment of the first and second parts, where the parts fit together so that the threads on the external surfaces of the parts form a continuous thread.

A method of manufacturing a welding stud. The welding stud comprises a weldable portion of light metal and a functional portion of steel. The method comprises the steps of: providing a welding part of a light metal and partially defining a recess, providing a function part of a steel and which includes a protrusion, providing a press with a die and a punch, arranging the welding part on the die and the function part on the press such that the protrusion opposes the recess, and manufacturing the welding stud by impacting the welding part and the function part into the die by the punch such that the protrusion enters the recess and the welding portion forms a sleeve around an end of the function portion to form the welding stud with the welding part forming the weldable portion and the function part forming the functional portion.

A connecting element for fastening connection pieces to fiber composite components made of at least one fiber layer and of matrix material is provided, the connecting element has a screw- or bolt-like shape, the connecting element includes a tip at one end thereof, which tip supports the penetration of the fiber layers of the fiber composite component in the dry or matrix-impregnated, unconsolidated state, and comprising a casing in the region that comes in contact with matrix material of the fiber composite component, but at least in the region that comes in contact with the reinforcing fibers of the fiber composite component.
