The LTS thread has a non-runout design of round thread, which is characterized by its easy connection, good tightness, simple maintenance and low price. Each has eight round crested thread per inch, which is the same as the STC type. LTC thread is well used where some axial load needed but overall well conditions do not include extremes of temperature or pressure.
