All I found was some other links regarding reducing torque for wet or oiled fittings. They suggest reducing the spec dry torque by 10-25% depending on source. They also note that torque should not be reduced if Loctite or similar is applied, but it just doesn't feel right:bowdown:

Here's a page with a diagram showing the components of the torque in tightening nuts and bolts. A small change in turning friction can cause a huge change in the stretching component, which can have a tremendous impact on the tightness and safety of the bolt.

The chart here shows how the recommended torque varies widely based on the strength of the steel in the fastener.

These variables show why it is important to pay attention to the manual specifications. It's easy to over torque or under torque a fastener. Put too great a torque on soft steel you'll have failure. Put insufficient torque on high strength steel fastener and you can have a failure.
