Herein disclosed is a mechanism for providing high load capabilities in downhole locations. The mechanism comprises tubulars, at least one of which is constructed from composite; and the tubular composite being for high load capabilities in connecting the tubulars. In some cases, there are at least two tubulars in the mechanism. In some cases, the mechanism comprises a thread form, which thread form is mounted to translate an axially directed force into a radially directed force. In some cases, the high load capabilities include a load bearing flank angle of 15° to 50° as measured from the axis of said tubular. In some cases, the high load capabilities include a clearance flank angle of 15° or less as measured perpendicular to the axis of said tubular. In some cases, at least one of the tubulars includes a thread pitch, having from 2 to 12 threads per inch.
