I torque to 150 ft-lbs and have never pulled the thread in the nut. That is over 150 engines. Never had one come loose either. Red and white torque also works (face turns red and knuckles turn white).

In a previous thread, offset threads were mentioned as original. IMO during the lifetime of the cam, someone did a little hammer work on the threads to make sure the gear didn't loosen up over time. Have used the new, original style nuts and they screw on the camshaft by hand with no problem.
