12v Impact Wrenches

Does anyone use a 12v impact wrench on their rig? I'm thinking about getting one from Amazon for about $50.00. It is supposed to have 240 f/lbs of torque but is that strong enough to take off the lugs on a class c dually? Tnx
  • I use the 120v Craftsman unit. Works good for me. I think it is 350'#.
    I run it with my 1800w inverter but maybe your generator would run it fine.
    I don't like the idea of having to charge that little battery for 30 minutes on the side of the road.

    I carry a Milwaukee 18v 1/2" drive impact the kids got me for Father's Day. It's a beast though, over 400 ft lbs of torque and can break studs/lug nuts off if you're not careful. I carry it because I can handle anything from broken suspension and more. Pricey; over 3 bills.

    Having said that, any major brand 18v will work just fine for you. I used to use a 18v Hitachi drill that I got on sale at a good price and it worked fine.
  • I use a drill...I cannot stand the sound of impacts while i'm camping, so I figured I wouldn't do it to others
  • The 12V may work for the sissor jacks because they're not tightened down, but it won't break youir lug nuts loose. After you break them loose by hand, it should be able to spin them off, but what do youi really gain but more weight to haul around? My 18V Dewalt will break the lugs loose on my mother's car, but not my F250. I really don't think it will break them loose on your dually tires either.

  • I use a DeWalt 12 volt impact driver for my scissor jacks.
    NO PROBLEM at all, plenty of power
  • I'm using a 18v black and decker to do my stabilizers with and it's not an expensive one by any means. Something with that much torque, I'm thinking that your going to want at least 18 volts and likely 350 ft/lbs or more. Just get a couple batteries so you can always have one on the charger while the other is working.
