I still need a little clarification on prevaililing. According to the table you have a link to:
The torque required to run a nut down a thread on certain types of nuts designed to resist vibration loosening. The resistance can be provided by a plastic insert or a noncircular head
Does this mean that when Loctite 271 has been used that it will take 275 F-lb (N-m ?) for a bolt to unscrew?
