The connection between nut torque and bolt tension
The nut torque stated in bolt tension tables is based on lubricating threads with light oil. When another lubricant is used the torque values must be adjusted to get the 65% to 75% yield stress recommended for bolted connections. The ease with which a nut moves on a bolt thread affects the torque required for it to turn.
