Torque specifications are given for clean, dry threads unless otherwise
specified. That's true for SAE, DIN, and JIS standards, as well as the
aviation industry.

Example: "Be sure the bolt and nut threads are clean and dry, unless
otherwise specified by the manufacturer." (FAA AC 43.13-1B, 7-40b)

SAE J1701M specifies torque reduced by ~25% for lubricated fasteners.
