ABSTRACT:
A dowel, arranged to secure an article to the surface of a receiving material having a hollow space within it into which the dowel extends, is formed of an axially elongated dowel body and a flange member at one end of the dowel body. The flange member includes a flange part extending transversely outwardly of the dowel body. The dowel body is formed from a strip of material and includes an end part extending transversely of the axial direction of the dowel body with a threaded opening through the end part, and a pair of axially extending legs divided into webs and extending in the axial direction of the dowel body from the end part. Inwardly directed recesses are formed in the ends of the legs spaced from the end part. The flange member includes a sleeve-shaped projection extending generally perpendicularly of the flange part. The sleeve-shaped projection fits into the ends of the legs, and the dowel body and flange member are welded together at the locations where the recesses in the legs contact the sleeve-shaped projection on the flange member.
