Just got back. She said the hammer them to about 50, then hand torque to spec.

I zap them on. I used to torque....then got comfy with the gun I use and each time I'm pretty on the money. Maybe a difference of 5 lbs at most, which isn't significant. For guys like Russ that are breaking studs.. you need to get a better length tool for the job. Either you are too strong, applying too much force or your tool is too long and gives you too much leverage.
using air tools simply speeds up the process and so long as you do it "correctly" then you shouldn't have any issues.
if you sit there and pound them on forever after they've stopped moving you're likely to break something. it only needs to get hit a few times once 'tight'.
And this is exactly why I use a torque wrench. Because of my tool & die training, it's habit to tighten things is tight as humanly possible. Just before the point where the screw/bolt snaps. You don't want something shaking loose in a die running 200 strokes per minute!
For me, the torque wrench serves as a restraint.
there's some bolts you can go german on (gudentite), but even the ones you shouldn't using a torque wrench a lot of the time is a waste of resources and time.
besides head studs/bolts on a motor i do the rest of the crap by feel...
^^That.
I don't even torque the LIM and blower.
On it goes. The end.
I've never torqued a lug nut either; then again...hindsight...I make sure hubs are torqued properly though. That's a big deal.
Maybe I just like the "click" my wrench makes.
No, seriously, if I wrenched for a living or was flat rate or something like that, I'm sure the clicker would get used a lot less. However, as someone who's still a noob, using a torque wrench eliminates at least one thing to worry about when I'm fumbling my way through a job.
For me, the repairs are more of a hobby.
The shop I used to work at, we had issues with a few tech's not doing as they were told. Shortly after I left, I heard that they had a major issue; one of the tech's that thought he knew better, didn't torque a customers wheels after a service. Said customers wife picked up the truck, drove a few miles across a major bridge (100' tall), and the right front wheel came off and launched off the bridge. The shop had the truck towed back to the shop and they got it all fixed up. One of the owners went below the bridge to the area where the tire should have been, but couldn't locate it (there are shops and restaurants there). Needless to say, the tech was relieved of his duties, and the other techs magically started doing as they were told. Lesson learned, the hard way.
I think the correct IMPACT your looking for is in the picture below

I tried torquing a lim bolt one time, it snapped off before I even heard the torque wrench click. Luckily I was able to get it out and I just got them all on nice and right.
