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

(1) Values are FOR REFERENCE only. Daniel provides the torque values in this table to help users
establish a starting point to achieve an adequate unit assembly clamping force. Torque values
reflect threads and nut bearing surfaces being bare metal well-lubricated with thread compound
assembled in a controlled factory environment.
(2) The final torque required to achieve an adequate seal may be higher or lower than the range
provided in this Table
