ABSTRACT OF THE DISCLOSURE A method of making a shackle bow for use under great loads, such as in anchor lines. The shackle is formed from a cylindrical bar rod by fullering the ends to a reduced diameter, and forging the central portion into a flattened shape having the cross- section of a wide shallow U shape. The bottom inner surface of the central section is in the form of a portion of a circular cylinder. The ends of the bar are flattened to form end hubs with a central opening for a pin. The formed bar is then bent in the form of a bow to provide an eye for the shackle, with two parallel end hubs spaced a selected distance apart.
