You have got to reread the post, I advised to use a torque wrench if you don’t wrench a lot. When people say tighten things up, then to some that means reefing on them as you put it, if they are already tight they think tightening them more is what is required to stop the leak. Is that understandable, you risk overtightening already tight bolts, unless your experienced. Let a apprentice do this and you will see him grab a breaker bar and snap away. Sounds mad but I have seen mistakes like this.
Ok, I see what you are saying now.
I think of the average person grabbing their cheap 3/8" socket set and snugging them up. Not grabbing a 1/2" breaker bar and going to town.
