Re: 'Impacts are not a bad thing if you use some brains.'
Oh yeah!! Well
I use one!!!!
Kind'a blows THAT idea out of the water, 'eh?
Whatever kind/type/model you get, DO some checking on what it actually tightens to and how much 'trigger' it takes to get you there.
Test it on some 'safe' fasteners, backed up with a good torque wrench.
Ex: Put a lug nut on your rig, tighten it with your new wrench. Use your manual torque wrench to see what it torqued to.
BTW...repeated 'testing' of the same fastener with ever increasing torque settings will further tighten the fastener from what it was first torqued to. Well, 'refastening' the same fastener will change its required/applied torque, too.
The only reason I bring up any of that is to preclude someone saying, 'Yeah...but...'
to the 'test it' idea.
I use an air impact. I take into account the tank pressure
and the settings on the wrench whenever I use it. I know what it does within a couple ft/lbs.
A story for you...why you need to know.
My riding buddy used his new SnapOn battery-operated torque wrench (adjustable) to tighten his flywheel once. Five minutes into the next ride, he sheared the key.
Guess it weren't tight enough, huh?

The new (expensive, premium branded) wrench SAID it was!!
Test it!
Yes...that all has to do with tightening a fastener.
Loosening something? It will work fine...as long as you use some brains....
