Selected answer:pin-down assembly (pin pointing downwards)
Explanation:
The references below explain it quite well:

The bulk of the drill string is drill pipe...
Steel pipe has a "male" connection at one end (called the pin) and a "female" connection at the other end (called the box) and as each section of pipe is lowered into the hole it is connected to the pipe preceding it by threading together the male and female components.
http://en.wikipedia.org/wiki/Driller's_depth

The sections of drillpipe are generally assembled in a pin-down configuration and, together with the BHA, form the drillstring. linkinghub.elsevier.com/retrieve/pii/1350630794900108

Bit subs
Bit subs are used to connect the drill bit to the next piece of equipment in the BHA. Because drill bits are “pin up” and all other drilling components are typically “pin down”, the bit sub functions as a crossover for BHA attachment.

Explanation:
I believe I ran into the source text related to your question above. Pin down here means to fix or establish clearly, meaning it is firm and easy to set your target and does not move or sway.
