1. A threaded connection for hammering interconnected tubular members into a ground that comprises onshore land or offshore seabed for exploration and production of a hydrocarbon well, comprising:
a pin member comprising an external shoulder, a pin nose, a tapered pin threaded portion located between the external shoulder and the pin nose, and a sealing surface located between the pin nose and the pin threaded portion;
a box member comprising an internal shoulder, a box nose, a tapered box threaded portion located between the internal shoulder and the box nose, and an elastomeric sealing member located between the internal shoulder and the box threaded portion, where
the pin threaded portion and the box threaded portion are configured to engage each other during rotational make-up of the threaded connection,
the pin threaded portion and the box threaded portion comprise hooked threads providing radial interference between at least one of (1) crests of the pin threaded portion and roots of the box threaded portion or (2) crests of the box threaded portion and roots of the pin threaded portion, at final make-up of the threaded connection, wherein the hooked threads comprise a positive stab flank angle and a negative load flank angle,
facing load flanks of the hooked threads of the pin threaded portion and the box threaded portion are in contact with each other at final make-up of the threaded connection,
facing stab flanks of the hooked threads of the pin threaded portion and the box threaded portion are located at a flank distance from each other at final make-up of the threaded connection,
the sealing surface and the elastomeric sealing member are configured to form a radial seal at final make-up of the threaded connection,
the box nose is in contact with the external shoulder at final make-up of the threaded connection,
the pin nose is located at a shoulder distance from the internal shoulder at final make-up of the threaded connection, and
the elastomeric sealing member is spaced apart from the tapered pin threaded portion at final make-up of the threaded connection.
