Bolts should be systematically tightened starting
from the most rigid part of the joint.

Table 9.2. Follow a crisscross pattern (Ref Fig. 9-3)
and tighten remaining bolts to 1/3 of final torque.
Step 2. Repeat pattern and tighten all bolts until 2/3
of the specified torque is reached.
Step 3. Continue crisscross pattern and tighten until
