Page 39 - D is the actual external diameter 71 of the tube throughout its parallel length, and is expressed in inches. Further back, beyond the perfect threads, come two having the same taper at the bottom, but imperfect at the top. The remaining imperfect portion of the screw-thread, furthest back from the extremity of the tube, is not essential in any way to this system of joint ; and its imperfection is simply incidental to the process of cutting the thread at a single operation. From the foregoing it follows...
