Abstract

The dowel with a threaded sleeve is formed from a punched flat sheet-metal blank (10), in the end section (14) of which, intended for forming the threaded sleeve, parallel rows of studs (15, 16) are formed as punched protuberances. The studs (15, 16) run obliquely to the longitudinal direction of the sheet-metal blank (10), so that, after formation of the threaded sleeve (21) from the sheet-metal blank (10), they lie on a helix for forming a thread. The studs (15, 16) of circular cross-section are expediently frustoconical. Two parallel rows of studs are sufficient for forming a thread. The dowel body, which is connected in one piece with the threaded sleeve and is formed from the same sheet-metal blank (10), has adjoining the end section (14) of the sheet-metal blank (10) individual staged sheet-metal strips (11), which bend out under the tensile force of a screw screwed in from the other end, folded over outwards to form a collar.
