Buttress thread connections are made up to correct "torque" by burying half of the stamped triangle one the Casing pin end. As a rule the torque will vary a few hundred foot pounds either way.

A good habit is to always use this method, but if the client requires a torque figure then and average torque reading over 10 connections can be used as a indicator but this could end up with a previously run connection not sealing due to "run in" deformation and this is highly undesirable.
