7.2.8.4 The “snug tight” tension shall be approximately 15 percent of the specified tension and
shall be achieved using a calibrated wrench.
7.2.8.5 The sequence of bolt tensioning shall be shown on the drawings.
7.2.8.6 After the snug tight condition is achieved, an initial tension of 75 percent of the final
tension shall be developed in all the bolts. Only then shall the final tension be developed.
7.2.8.7 The final tension shall be verified by testing 10 percent of the bolts after all the bolts are
tensioned. If the verification indicates loss of tension in some bolts, the Contractor shall notify
Engineer. The Engineer and the Contractor will develop the appropriate action.
7.2.8.8 The flange contact bearing surfaces shall have at least 75% of the bearing cross-sectional
area in contact. The outer surface of the flanges shall fit within 0.010 in. (0.25 mm) for 75% of the
length of the edge and not more than 1/32 in. (1 mm) for the remaining 25% of the length.
7.2.8.9 Bolt tension may be verified at locations selected by the Engineer. Bolt tension
verification shall be performed by the Contractor in the presence of the Engineer and in such a
manner that the Engineer can read the torque wrench gage during verification.
