ABSTRACT:
A sucker rod connection is disclosed. The sucker rod connection comprises a tapered male member including a plurality of trapezoidal threads, and, a tapered female member also including a plurality of trapezoidal threads, in which the male member is capable of being received in threaded engagement with the female member, wherein the threads of the male member are in flank-to-flank contact, both flanks on each thread, with the threads of the female member, thereby creating diametrical interference between the male and female members preventing disengagement and substantially reducing axial interference between the male and female members.
