Abstract: One-way chain for an aircraft tie-down, as well as a method of making one-way chain. The method preferably includes the steps of providing an unmodified welded chain having a plurality of welded links; feeding the unmodified chain into an automated shaping machine constructed and arranged to shape the welded links in separate shaping events; and individually shaping the welded links to form shaped links in a series of separate shaping events that shape the respective welded links so that a first width of a forward end of the respective shaped link is narrower than a second width of the greatest planar width of a rearward end of the respective shaped link; such that the forward end is sized to fit into a link receiving receptacle of a screw-type binder mechanism and the rearward end will not fit into the link receiving receptacle.
