Diff U bolt torque spec

Hellooooooo FABO,

I have seen mentions of 45ft/lbs for U bolt spec.

When i get out the ol torque wrench and start in on it (snap on click type....side note, 45 ft/lbs is the LOWEST setting), using as smooth sweeping steady motion as i can..... 45 seems like A LOT!! I feel like its gonna start distorting the tube.

What about navy torque and a smidge of loctite medium??

What say ewe?

Also, the U bolts are not new, and i am using flat washers.

Thanks FABO!!
