just to get it to seat on the taper. Torque down proper after. Guess you recommend a wrench and the allen key
I don't have a lot of experience with air tools, but I've taken things apart after they've been assembled with air tools... like the bolt that holds my brake hose onto the knuckle that a mechanic ran in cross threaded. I'm not saying you would cross thread it, but it could very well end up overtight and you wouldn't know it. I didn't realize you intended to torque it afterwards..... I'd back it off first. I've used a standard (non-locking) nut to seat tapers before. Usually, I don't have much of an issue with new parts since they tend to be stiff enough to not spin.
