Can I torque my wheels with an impact?

I use my 1/2 Milwaukee to R&R wheels on my truck and battery usage isn't to bad really.
To the original question if you are worried about torque buy a torque wrench. Listen to what ppl here are telling you. They know more than you

 

My Milwaukee has advertised torque of 1000ft/lbs. It doesn't come close to that in reality

 

I would check it with a torque wrench to be safe

 

Use a torque stick on the impact, then final-tighten to spec with a calibrated torque wrench.

 

A lot of talk about torque here. No mention of, but just as important is to tighten in a criss-cross pattern and in increments.

 

I would use a proper torque wrench.

 

Its kinda funny when you compare a 1/2" to a 3/4" or 1" drive. I j ust picked up a new Aircat 1/2" impact. Almost 1,300 ft-lbs reverse and 900 ft-lbs forward. The shop has an older 3/4" gun with about 1,000 ft-lb in reverse. It will take stuff apart my Aircat won't. The bigger gun just hits harder than the smaller one.

 

You will get the feel of it. Just you the impact to get em tight, a few ughadugahs. Then switch to the torque wrench
