The threaded connection for the oil country tubular goods, according to the invention, has excellent gas tightness and crevice corrosion resistance. Moreover, the production cost thereof is equivalent to that of conventional threaded connections and it is easy to handle. Hence, it is quite suited for use in exploration and exploitation of deposits located at great depths under high pressures and deposits such as gas, crude oil, or the like containing highly corrosive impurities.

[ We claim:] [1.] A threaded connection for tubular goods, wherein a seal portion is formed by fitting a seal forming face (13), provided on an outer surface of an end portion of a pin (11) of a pipe body, with male threads formed thereon, into a seal forming face (23), provided on an inner surface
[ We claim:] [1.] A threaded connection for tubular goods, wherein a seal portion is formed by fitting a seal forming face (13), provided on an outer surface of an end portion of a pin (11) of a pipe body, with male threads formed thereon, into a seal forming face (23), provided on an inner surface of a box (21) of a coupling or a pipe body, with female threads formed thereon, while an internal shoulder is formed by butting a torque shoulder forming face (14), provided at a tip of the pin against a torque shoulder forming face (24) provided on the box, opposite to the torque shoulder forming face (14), said threaded connection for the tubular goods satisfying the following conditions (1) and (2):(1) The seal forming face on the pin and box, respectively, is a rotatable face, and a pitch diameter of the seal forming face (13) on the pin, prior to making up the threaded connection, is larger than a pitch diameter of the seal forming face (23) on the box, prior to making up the threaded connection; and(2) An inclination (.theta.1), measured from a plane perpendicular to an axis of the coupling or the pipe, of the torque shoulder forming face on the pin, prior to making up the threaded connection, is smaller than an inclination (.theta.2), measured from a plane perpendicular to an axis of the coupling or the pipe, of the torque shoulder forming face on the box, prior to making up the threaded connection, the difference (.DELTA..theta.) between the both inclinations being in the range of 0.5 to 4.0.degree..
