1. An electrically conductive transformer stud connector comprising:
a connector body having an elongate passageway therethrough, said passageway having a threaded region defining first and second connector threads having different thread sizes for accommodating tranformer studs having two different stud threads and defining a stud threadform angle;
said first and second connector threads being overlaid tangentially along said passageway and defining thread roots and crests wherein said thread roots of said first and second connector threads are aligned and said thread crests of said first and second connector threads are non-aligned and wherein said connector threads further include thread flanks connecting said thread roots through said thread crests, said flanks diverge from said roots to form a connector threadform angle;
said connector threadform angle is different from said stud threadform angle so as to provide two lines of contact between said stud threads and said connector threads.
