Abstract
A method and system certifies a joint between a first threaded element having a first shoulder and a second threaded element having a second shoulder and the equipment used to tighten the connection. The method tightens to a first position at which the first shoulder abuts the second shoulder. Marks are made that are aligned across the first element and the second element corresponding to the first position. The connection is loosened and then tightened to a second position complying with a predetermined tightening specification. The distance beyond the marks for the first position is measured to verify that it is within acceptable tolerances. If acceptable the connection and/or the tightening equipment can be certified.
