ABSTRACT:
Two mechanical components are interconnected, for example, the two principal parts of a pedal rod by forming the clevis with a progressive die so that threaded portions are provided on opposite sides of an opening and are formed and shaped strictly by compression without rotation. The work piece is then folded so that the threaded portions are in register and the shaft part of the pedal rod is threaded in place and adjusted to take up the tolerances in the linkage. The two parts are locked together either by crimping, spot welding or by a lock nut, or by joining out of sync thread segments.
