Mechanics Using Cordless Drivers - Over Torque?

I think people are only complaining about bolts that should be field removable, but are not. i.e. lug nuts at 300 lb-ft. Taking a bit of care in this one area is not an unreasonable expectation.

I do not care about the torque on my starter bolts. And I don't care if he uses power tools to save time.

And unfortunate as well.

Not even close to being analogous.

Right, but turn down the torque.

I was just kidding , but not really . Here , every critical fastener , gets torqued to factory spec, including wheels, every time without exception
I never finish tightening with cordless tools, always done by hand. There are however, lots of non critical fasteners , that just get blasted in the 3/8" impact, and final tightened with my calibrated arm.
The alternator bracket , or transmission crossmember on your rusty pickup does not really care how tight they are . The spec for things like that is guten tite. I have a cordless screwdriver that I use to run belly pan screws in . They are a pain for all of us .

I watched a factory gm mechanic, re assemble a warranty motor job, with no torque wrench, mains, rods, heads etc, air gun, blap, blap , blap . Guy was lighting fast, and made big money , but that is just wrong .

I use a cordless drill to run nuts on many times because you can adjust the torque.
And then while trying to remove a rusted on bolt after soaking it in penetrating oil, I still broke my extension with my impact driver.
