Abstract: A tubular member having a first connector provided on a first end thereof, this first connector being adapted to receive a corresponding connector provided on another tubular member, forming a tubular connection comprising: a pin connector, a box connector, an outer diameter, an inner diameter, and a longitudinal axis. The pin connector threads or box connector threads feature a threadform having at least one load flank reduction zone such that when the pin connector is threadably engaged with the box connector, the resulting tubular connection radial bearing strength is desirably reduced. More specifically in the preferred embodiment, the at least one load flank reduction zone is preferably configured such that the tubular connection radial bearing strength is between 100% to 110% of the cross sectional connection strength when the box connector is threadably engaged with a pin connector.

Abstract: A threaded connection between adjacent drill string components comprises a threaded female connection end adapted to receive a correspondingly threaded male connection end, the two ends each having first and second portions of different tapers. Tubular members, drill string tools and other drill string components comprising the female or male ends described herein are also provided.
