to add to the discussion - if one goes to an engineering book on torque values, it is not just the fastener but what it fastens too. I LMAO when someone lectures some of us in some car forum about how the bolts must always be dry, then they screw it into an oily hole in the block. Torque settings also have a range, often the published spec is simply the middle of that range. Sometimes three different versions of a service manual will have different values for torque, sometimes in the same manual. Page XYZ will say 23 ft lbs for something, page WXY will say 18 ft lbs and the photo page of an assembly with arrows and specs to fasteners will say 29 ft lbs. Last, how many people here send their torque wrenches out once in awhile to be cleaned and recalibrated. I do because working in the machine shop I learned that most torque wrenches over time, other than the old style single beam wrenches, can drift enough to snap bolts or have them come loose later. TeamTorque is who I send my wrenches too.
