Recommended Bolt Tightening Procedure
1. Start with all fasteners hand‐tight.
2. Progressively tighten all fasteners in a standard criss‐cross pattern. Use multiple passes of increasing torque
increments until the maximum desired torque has been reached.
3. Make the final passes in a circular pattern until there is no bolt movement at the maximum torque for 1 complete
pass.
4. For steam service and other high temperature applications, it is beneficial if the unit(s) can be heated up and then
cooled down after step 3, and then step 3 repeated.
Lubrication Recommendations
NCF2 coated fasteners can be used either with or without additional lubrication:
D If the fasteners are used without additional lubricant, use the torque values for uncoated fasteners with Molykote
321R Spray‐Bonded Lubricant or equivalent.

R
D If additional lubricant is applied to the NCF2 coated fasteners, use the torque values for the lubricant that is being
used.

Recommended Pipe Plug Installation Procedure
Torque values are not used when tightening NPT pipe threaded connections. Rather, we follow American National
Standard ANSI / ASME B1.20.1, where thread engagement is used to determine how much to tighten the connection.
Refer to Fig. 3 and Table 2 of the standard. Thread the pipe plug in by hand as far as possible, and, using a wrench,
tighten the additional number of turns specified in Table 2 (column 15) of the standard.
