The Torque Safety Joint is a threaded joint that can be separated downhole by applying torque to the work string. It provides a controlled release point in the event of a stuck bottom hole assembly. When the joint is released, a coarse thread is exposed at the top of the section that remains in the well. An included retrieval tool can be threaded into the retrieval thread to permit jarring and fishing operations using the same work string.
Right-hand and left-hand release versions are available.
