摘要

The casting, particularly metal die cast piece, has a passage hole (2), which is provided for receiving a screw or a threaded bolt, and a thread formed in the passage hole. The thread is formed by a thread ribs (3) provided with other inner cover spaced axially from the openings of the passage hole. The threaded ribs runs over a circular arc with corresponding pitch forming the thread and the ends that are formed by a stage (4). An independent claim is also mold for the formation of a casting, which has two half-molds with a cavity.
