  • Pre-installed anti-rotation key for threaded connectors
    Patent number: 10597950
    Abstract: A tubular member connection system includes a pin having a central axis, external pin threads, and an annular pin lip at a shoulder surface. A box has internal box threads and an annular box lip 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 recess is formed in an outer diameter surface of the pin and extends in an axial direction from the pin lip. An anti-rotation key is located within the recess and has a row of teeth along an outer edge. A fastener retains the anti-rotation key in the recess. A circumferentially extending series of grooves on the box lip are sized to engage the teeth and resist a rotation of the pin relative to the box in an unscrewing direction when the pin is releasably secured to the box.
