    The geometry is not practical for forging. The height to thickness ration of the flat flange area is not possible.

    Why forging as one piece?
    Tell me and I forget. Teach me and I remember. Involve me and I learn.

    Why not a full strength, full penetration weld to make it a captive nut, rather than a single entity?
