Method and means of manufacturing ties, fasteners and rods (15) having a plurality of longitudinal threads by forcing a coil of roll-profiled feed-wire made of steel (11) through a twisting-die made of plastic (1). Also described is: a twisting-die made of plastic (1) that is suitable for twisting profiled feed-wire (11) made of steel; a method of forming a plastic twisting die (1) using an driven tap (31) in the form of a twisted rod (15); and a helically-shaped member (15) having lead measurements (X) along the length of the helical thread that vary less than pitch measurements (Y) along the lengths of the helical threads.

The invention relates to a connection element, in particular a thermal adhesive bonding boss, to be introduced into at least one component, in particular a hollow chamber component, in particular a plate-shaped hollow chamber component which has hollow chambers, under the effect of pressure and rotation, comprising a main part which comprises a thermoplastic synthetic material. The connection element has a longitudinal axis and is designed to rotate about the longitudinal axis, and the connection element has an upper face with a tool placement point and a lower face which faces away from the upper face, wherein the connection element has an expanding portion made of a thermally activatable expandable material on the main part on a circumferential surface extending between the upper face and the lower face.

A profile system includes a series of elongate profiles (1) and one or more intermediate and/or end elements (8; 28). A series of connecting pins (14) each are a separate part having two end portions (15, 16) and being designed to releasably connect a profile (1) on the face side with an intermediate and/or with an end element (8; 28). The profile cross sections form on their face side receiving openings (5) for receiving the first end portion (15) of a connecting pin (14). The intermediate and/or end elements (8; 28) comprise receiving holes (13) for receiving the second end portion (16) of a connecting pin (14). The receiving openings (13) of the intermediate and/or end elements (8; 28) each extend through a wall into a cavity of the intermediate and/or end element (8; 28).

A clip is attached such that a leg portion protruding downward from a head portion is inserted into a cylindrical insertion hole of an attachment-target member. The clip has a plurality of engagement protrusions protruding from the leg portion and arranged in an insertion direction. The engagement protrusions have engagement corners sharpened to have a corner radius less than 0.2 mm. At the time of insertion into the insertion hole, the engagement corners slide on an inner circumferential wall surface while the engagement protrusions are elastically deformed. After the insertion, the engagement protrusions are elastically restored to dig into the inner circumferential wall surface, thereby preventing the clip from coming off from the insertion hole.

Amorphous calcium carbonate is included in a fire-resistant inorganic mortar system for a fire-resistant chemical fastening of anchors and post-installed reinforcing bars in mineral substrates. The system includes a curable aluminous cement component A and an initiator component B for initiating the curing process. The component A includes at least one blocking agent selected from the group of phosphoric acid, metaphosphoric acid, phosphorous acid and phosphoric acids, at least one plasticizer and water. The component B includes an initiator, at least one retarder, at least one mineral filler and water. Moreover, amorphous calcium carbonate in a fire-resistant inorganic mortar increases load values. Also, a method is used for a fire-resistant chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone.

An airfoil a metal body, a cover panel carried on the metal body, and push fasteners extending through the cover panel and locking the cover panel on the metal body.

A fastening apparatus for fastening a component to a carrier component includes a housing device having a receiving recess, at least one actuating element and at least one latching element for latching in a carrier component, and a pin device which can be arranged so as to be displaceable in the receiving recess of the housing device in an assembly direction and which has at least one movable pin arm with a pin latching structure for transmitting an assembly force, which acts in the assembly direction, to a rigid housing latching structure which is integrally formed on the housing device, in order preferably to arrange the fastening apparatus in an intermediate assembly position, wherein the housing latching structure is formed in a corresponding manner to the pin latching structure, and wherein the actuating element is designed to actuate the at least one pin arm.
