METHOD FOR SCREWING A THREAD-CUTTING SCREW INTO A DRILLED HOLE AND THREAD-CUTTING SCREW FOR CARRYING OUT THIS METHOD

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.
