Abstract

A coupling for connecting downhole tubulars, comprising a tubular body; a female coupling part; a male coupling part; and at least one of: a male screw thread formed on an outer surface of the body, and a female screw thread formed in an inner surface of the body, wherein: the at least one thread has a thread-form including a crest, a root, and a pair of flanks, the crest and the root are each cambered about a respective first and second camber radius, R<sub>b</sub>, R<sub>b</sub>-T along the entire length of the thread-form, and each camber radius, R<sub>b</sub>, R<sub>b</sub>-T, is greater than an outer diameter of the coupling; the male screw thread has a camber radius, R<sub>bm</sub>, and the female screw thread has a camber radius, R<sub>bf</sub>; characterized in that: each camber radius (R<sub>b</sub>, R<sub>b</sub>-T) is between 700 - 1900 mm.
