ABSTRACT:
The method of forming a nut-like member especially adapted but not limited to use with an earring clip in which a threaded screw provides wearing adjustment. The method includes forming a vertical strip of sheet-like material with a pair of smooth bore openings disposed in longitudinal alignment and provided with a pinched and reformed chordal flat. Thereafter the strip is transversely bent in a generally U-shaped configuration along a line between the openings so as to form a pair of opposed legs each including one of said openings.
