(54) Title: DROP IN ANTI-ROTATION KEY (57) : A tubular member connection system (11) includes a box (27) having an inner 49 diameter surface and internal box threads (29). A pin (15) has an outer diameter surface and external pin threads (17), the pin threads shaped to mate with the box threads to releasably secure the pin to the box so that the pin and the box are aligned along a common central axis (16). A slot (35) is located in one of the inner diameter surface and the outer diameter surface, 3/ the slot having a pair of side-walls (37). An anti-rotation profile (47) is located in the other of the inner diameter surface and the outer diameter surface. A key (41) is sized to fit within the slot and have a key profile shaped to engage the anti-rotation profile (47) and prevent relative rotational movement between the box and the pin.
