摘要： The invention relates to a securing element comprising an anchor bolt (1) with a shank (3) and a clamping wedge (2). The clamping wedge (2) comprises a break-off zone (15) which is defined by two mutually separate break-off points (25, 26). Said points run traverse to the mid-longitudinal-axis (6) and traverse to the support surface (12) of said clamping wedge (2) on the anchor bolt (1).

摘要： The invention relates to a corrosion-resistant, threading (1), especially concrete screw, for screwing into a bore-hole with a bore-hole-wall, comprising an essentially cylindrical core (2) consisting of corrosion-resistant metal, with a central longitudinal axis (8), a thread (5) which is configured as a single piece with the core (2), and at least one cutting element (9) with at least one cutting head (12) for cutting into and hereby engaging with the bore-hole. The at least one cutting element (9) is introduced into the core (2) and permanently connected to said core and consists of a hardened metal. The at least one cutting head (12) is situated in the thread (5).

摘要： The invention relates to a thread-cutting screw (1) which is used to screw into a wall (1a) of a borehole (1b). Said thread-cutting screw comprises an essentially cylindrical core (2) which is metal and which has a longitudinal centre axis (4), a thread (5) embodied as a single-piece with the core (2) and at least one cutting element (6, 7) which is arranged in the thread (5) for cutting operations in the borehole wall. The core (2) is made of a metal having a carbon content of between 0 and 0.5 wt.- %. The at least one cutting part (6, 7) is securely connected to the core (2) and is embodied as a welded body made of metal having a carbon content which is greater than 0.8 wt. %. The cutting part (6, 7) ensures efficient cutting with a secure connection to the core (2) and the danger of a brittle fracture to the screw (1) is totally avoided.

摘要： A screw is introduced into a drilled hole (6) in a solid but porous material (7), especially concrete, in a sealed manner by means of pushing a cartridge (17) into said drilled hole (6) and then screwing the thread-cutting screw (1) in. A sealing agent (19) that is contained in the cartridge (17) is pressed into a channel (21) configured between the wall (16) of the drilled hole and the core (2) of the screw (1) and into the surrounding material (7), under pressure.

摘要： The invention relates to a screw (1), especially a concrete screw, for screwing into a borehole (20) with a borehole wall (25). Said screw comprises a body (2) having an insertion end (3), a screw down longitudinal direction (5) and a center longitudinal axis (4) and has a thread (7) configured as one-piece with the body (2). Said thread comprises a cutting thread (9) which extends from the insertion end (3) against the screw down longitudinal direction (5) and which has cutting thread flanks (12, 13) running in an essentially parallel manner in relation to one another, has cutting notches (17) which open in a radially outward manner, and a normal thread (11) which follows said cutting thread (9), whereby the normal thread (11) comprises an essentially triangular cross-section.
