Abstract: An expansion bolt including an anchor bolt having an expansion section, and further including an expansion sleeve which surrounds the anchor bolt and which can be expanded by retracting the expansion section, and a spring element arranged on the anchor bolt. The spring element can be tensioned by inserting the anchor bolt into a bore hole and can retract the expansion section of the anchor bolt into the expansion sleeve when it is released. An indicator element indicates when a rated tension of the spring element is reached.

Abstract: A sensor arrangement, for example, on an anchor bolt, including at least one sensor (10). At least one bypass element (20) with a dilatant material is arranged in the area of the sensor (10), whereby impact forces that act upon the sensor (10) can be dissipated via the dilatant material of the bypass element (20).

Abstract: A direct tension indicator (2), including a base element (11) and a cover element (13) that is arranged on the base element (11) and at least one indicator element (4) that is arranged between the base element (11) and the cover element (13) in order to display an axial force acting between the base element and the cover element. The indicator element (4) includes a dilatant material.

Abstract: A torsion bar for limiting torque, including a shank with a first end section and a second end section situated opposite from it in the lengthwise direction, also including a first coupler to non-rotatably join the shank to the driven spindle of an impact driver, whereby the first coupler is located on the first end section of the shank, and including a second coupler to non-rotatably join the shank to a threaded element, especially the nut of an expansion anchor, whereby the second coupler is arranged on the second end section of the shank, whereby the shank has at least one tapered torsion section in which the shank has a smaller cross section than in at least one of the end sections, characterized in that the shank has a plastic encapsulation, at least in the tapered torsion section.

Abstract: A method for the production of torque-limited fastening devices, which each have a first head element with a contact for a fastening tool, and a second head element that is joined to the first head element via a welded joint that shears off at a predefined limit torque, said method providing a plurality of first head elements and second head elements having the same geometry, and in each case, a first head element and a second head element are welded together in a welding process that creates the welded joint. At least two welding processes are carried out employing at least one different welding parameter, so that different limit torques can be obtained for parts having the same geometry. A fastening device on a concrete anchor.

Abstract: A fastening means is formed of an axially extending shank (1) and an expansion sleeve (3) that is expanded by an expansion cone (2) serving to anchor a member to a structural part. The shank (1) has on its leading end section in the setting direction a cross-sectionally reduced or reduced diameter section (4) to which the expansion cone (2) expanding in the setting direction is connected. The wall thickness (W) of the expansion sleeve (3) corresponds to 0.25 to 0.5 times the external diameter of the reduced diameter section (4). By using the solid construction of the expansion sleeve (3) high load capacities are gained in particular with loading of the anchorage opposite the setting direction (S).

Abstract: A fastening element including a stem (1) provided at one of its opposite end with a load application element (2) and at another of its end with a cone for expanding an expansion sleeve (4) at least partially surrounding the stem and having at least one longitudinal slot (6) that forming expansion segments (5) provided each with two locking elements (15) radially projecting beyond an outer contour of the expansion sleeve (4), arranged one behind another in the setting direction at a distance from each other, and having, in a plane extending through a longitudinal axis of the stem (1), a substantially uniform cross-section.
