A torque wrench is a precision instrument and requires a skilled craftsman to use it properly. Tightening bolted flange joints precisely to a predetermined torque setting requires a calibrated torque wrench to ensure that the job is performed correctly. Over-tightening or under-tightening any one or all of the fasteners can result in a leak. The only way to protect against either case with certainty is if a measurement of the torque is made when it is applied.
