Question 3264 Deck General

The correct answer is D) pin. The end of the joint with the exterior threads on a pipe or pipe fitting is called the "pin" end. This terminology is commonly used in the maritime industry, including the US Coast Guard, when discussing pipe fittings and connections. The other answer choices are incorrect because: A) box refers to the female end of the pipe joint, B) stem refers to the valve stem, and C) stand refers to a separate component used to support a pipe, not the pipe joint itself.
