Find the recommended tightening torque in Appendix 2. It is strongly recommended that a hydraulic torque wrench is used for final tightening. Follow these steps: 1. Tighten 'around the top' and proceed in the same sense as during pre-tightening. 2. Do the same operation for 'around the bottom'. 3. With the same torque, tighten all the nuts of each panel. 4. Re-check the interlocking of panels on girders.
