values, sequencing patterns and application rates provided here to achieve an adequate
seal.
Tighten each fastener at the following application rate:
•
Install Nut - apply less than 20% of the suggested torque
•
Second Pass - apply 20% - 30% of the suggested torque
•
Third Pass - apply 30% - 70% of the suggested torque
•
Fourth Pass - apply 100% of the suggested torque
•
Fifth Pass - apply 100% of the suggested torque four (4) hours after Fourth Pass
