Abstract
A drill string joint includes a box end member defining, at a first axial end thereof, a first bore and a second deeper bore of smaller cross section than the first bore. A pin end member defines a first insertion portion corresponding to the first bore and a second insertion portion corresponding to the second bore. A conical tapered surface interface is defined between the second insertion portion and the second bore. Cross pins extend through apertures formed through the box end member, at the first bore, and the first insertion portion, within an axial span of the joint separate from an axial span in which the conical tapered surface interface of the second insertion portion and the second bore is defined. A torque coupling is established between the box end member and the pin end member at an axial position between the separate axial spans.
