| For the six AWG and smaller I have a nice crimper that does a great job making hex shaped crimps. For the 2/0 and 4/0 cables, I just slide the ferrule onto the conductors, then insert the ferrule + conductors into the lug. And then tighten the set screw to the specified torque. As a test, I have removed the cable to see how the ferrule survived the set screw. The ferrule was not ripped and kept the wires inside. The wires fit the backside of the lug and were semicircular as proper and the set screw made a perfect spot for it to land onto the ferrule. I usually double check the torque at the end of doing the other wires to make sure the battery cables are secure. This method may not be scientific. I do have a battery cable crimper for regular lugs, but it make a diamond shaped crimp that doesn’t seem as nice as just using the set screw in the terminal.
