Table 2 - Dry Threads
The bolts should be tightened to the specified total value in increments, alternating from bolt to bolt to assure gradual, even pull-up of mating parts. Tightening should progress systematically from the most rigid part of a joint to its free edges. Circular bolt patterns should be tightened in a diametric crosshatch pattern while applying torque in increasing values to ensure proper pull-up of parts.
