Mike,
I was always told that when oil is used (wet torque) that the torque should be lower. I always clean my threads before torque (Dry torque). When I was in manufacturing our drawings would have a callout if oil should be applied, never apply oil on a standard torque (dry torque).
To each his own

Frank,
My 45 years working at a military contractor plant, if people started to apply lube/oil to all bolt thread at will, boy would that stop production and initiate a mass recall on installed hardware. Of course government drawing specs are more detailed for better control of design intent. Ha stripping out threads sells more replacement parts.
 
Every application is different, common sense should be applied, when selecting whether to use lube or not… as well as the conditions the fasteners must live in..
different conditions require different types of lubricants.
Dry torque does have its place, but to just blanket state that everything should be dry torqued is wrong.

IE: I would never dry torque a new set of rod bolts when building a BBC with steel rods..

But if I was bolting suspension hangers on an 18 wheeler chassis, chances are I wouldn’t use any lube..
Also whether the bolt is in shear or compression/tension comes into consideration as well..

Again, common sense applies..
To each his own…

Years ago I was next to butch the boatman and watched him tighten down cylinder allen head bolts
The t handle allen wrench bent 90 degrees further than the bolt turned,
I cringed, he saw the look on my face and said, hey kid that's how tight these heads gotta be!
I will never forget that one!

Common sense? What’s that?
