Letters used in the "Remarks» column mean:
- L: Apply a non-permanent locking agent to the threads.
- LG: Apply grease to the threads. Lh: Left-hand threads.
- M: Apply molybdenum disulfide grease.
- O: Apply oil to the threads and seating surface. S: Tighten the fasteners following the specified sequence.
- SS: Apply silicone sealant.
- St: Stake the fasteners to prevent loosening.
- R: Replacement parts.
The table below, relating tightening torque to thread diameter, lists the basic torque for the bolts and nuts. Use this table for only the bolts and nuts which do not require a specific torque value. All of the values are for use with dry solvent-cleaned threads.
