ABSTRACT:
A connection (20) for oilwell tubular joints (8 and 9) to effect a fluid tight conduit wherein one of two cooperating stop shoulders (19) of limited dimension is formed with peaks (22) and valleys (24) such that the peaks contact the other stop shoulder (18) upon full make-up of the connection so as to provide channels (24) for the escape of lubricant from between the shoulders and thereby effect a higher overload torque capacity for the connection, without sacrificing other characteristics of the connection.
