Abstract: A tubular member connection system (11) includes a pin (15), external pin threads (17), and an annular pin lip (21) at a shoulder surface (20) of the pin. A box (27) has internal box threads (29) and an annular box lip (31) at an end surface of the box. The box threads are shaped to mate with the pin threads to releasably secure the pin to the box. A pin recess (22) is formed in an outer diameter surface of the pin, the pin recess extending in an axial direction from the pin lip. A pin key (59) is selectively fastenable within the pin recess, the pin key having pin teeth (69) on an outer edge of the pin key. The box teeth (33) are located in the box. The box teeth (33) selectively mate with the pin teeth (69) and resist rotation of the pin relative to the box.
