    Abstract: A wear bushing assembly (20) protects and locks down a hanger (46) in a wellhead housing (45); and which includes a wear bushing body (22) that inserts into a wear bushing sleeve (34). A lock ring (40) extends into registered recesses (42, 44) on the body and sleeve to couple together the body and sleeve. The wellhead housing has a profiled recess circumscribing its inner surface. A lockdown ring (28) selectively mates with the profiled recess; and when mated is in interfering contact with an upper surface of the wear bushing sleeve, thereby coupling the sleeve to the wellhead housing. The sleeve outer surface is profiled to interfere with upward movement of the hanger, so that force is transferred from the hanger to the housing through the sleeve which locks down the housing.

    Abstract: An anti-rotation system for use in retaining a threaded connection between a pin and a box. The anti-rotation system includes a key that sets in a recess formed in one of the box or pin. The key is selectively in contact with one of the other of the box or pin, and is activated when the threaded connection begins to decouple. The key is profiled and operates in a cam like fashion to wedge itself between the box and pin when these members begin to decouple and prevents further relative rotation.
