The screwed insert (1) has a shaft body (2) designed to receive a threaded fixing element and with an outer cutting thread (3) and a terminal flange (19), and ends in a pre-boring element (20). This pre-boring element includes one or more boring legs (21, 22) that extend parallel to each other and are unsupported at their ends, and of which the radially inner and outer adjacent surfaces form a continuation of the wall of the shaft body (2) and a longitudinally aligned cutting edge (23). Each of these cutting edges (23) terminates in an outer cutting tip (28,29). A centring tip (34) is provided at the free end of a radially inwardly directed continuation (35) of one of the boring legs (22) and is able to be pushed to one side when a long fixing element (1) is advanced. The screwed insert demonstrates good boring performance and anchoring for example in a drywall panel and provides a fixing element or the engaging shank thereof with an engagement length that extends beyond the shaft body (2) as far as the at least one boring leg (21,22) that is unsupported at its end.
