A threaded connection includes an externally threaded pin connection and a n internally threaded box connection. The pin connection has a proximate end, a distal end, a pin shoulder at the proximate end and a distal contact surface at the distal end. The box connection has a proximate end, a distal end, an internal contact surface at the proximate end and an external shoulder at the distal end. At least one deformable element is positioned either between the pin shoulder of the pin connection and the external shoulder of the box connection or between the distal contact surface of the pin connection and t he internal contact surface of the box connection. The deformable element is of a softer materia l than that of the pin connection and the box connection, such that the deformable element deforms in response to a momentary torque overload.
