Abstract

A hose coupling fitting is furnished with a coupling head portion having a connecting hole, and a nipple portion having a nipple hole, and is fabricated through sequential cold forging steps carried out on a rod material. Specifically, a first pilot hole is formed along the center axis from a first end of the rod material, and a second pilot hole is formed along the center axis from the other end of the rod material. The second pilot hole is connected to the first pilot hole, and is formed with smaller diameter than the first pilot hole and larger diameter than the nipple hole. The surrounding area of the second pilot hole is then worked to form the nipple portion.
