12 volt impact wrench
Anyone tried one of these lighter plug impact wrenches? I got to
change a tire a couple weeks ago, and really coulda used an impact. But do they do any good, or are they all hype and no torque? -- Christopher A. Young You can't shout down a troll. You have to starve them. .. |

I would think that the spec is set to both ensure safety as far the lug nuts not coming off and protection of the threads on the lug nut and or stud. I'm guessing the installers don't even consider the possibility of damaging the nuts/studs and just assume tighter is better. Of course, this is all coming from a guy who tightens his lug nuts until they squeek. "Man, they sure sound tight!" g |

I'm with you, carrying the breaker bar. I've heard tell that some
shops have contests. See if Joe can put the lugs on so tight that Steve's wrench won't get em off. Of course, they end up replacing studs, rotors, drums, etc. The goal would be to get a rusted lug off after starting the motion with a breaker bar. -- Christopher A.

I did that a couple vehicles ago, changing shocks. The breaker bar
sheared off the bolt, and an impact wrench loosened the bolt. Ah, well. -- Christopher A. Young You can't shout down a troll. You have to starve them. .. "Mike Hartigan" wrote in message .net... The downside of using a breaker bar is that you're far more likely to break the bolt. An impact wrench is MUCH better for this situation. While I have never used a cordless impact wrench, I would tend to have little confidence in a 12V unit. Nevertheless, I will defer to someone who has actually used one. |

Being too far away from a 110 volt socket is why I was considering a
12 volter. For those once in a while moments when on the road. The corrections to what I wrote about foot pounds and price don't change the message very much. -- Christopher A.

(and $39.99 is the sale price.) big 750 Watt inverters are pretty cheap these days...get one that is at least twice the rated value of the impact wrench so it will start it reliably. I think an AC wrench and inverter would work much better than the 12 Volt job. A big inverter will draw LOTS of current , hook it directly to the battery, not to the cig lighter and maybe leave the engine running while using it. Mark |

12 volt impact wrench
Impact wrenches (all types: pneumatic, manual, electric) WORK.
They are safer than leverage when it comes to loosening nuts/bolts. OTOH than can easily over-tighten. In the "bad old days" the professionals used a "Cross" wrench. This always seemed to work a lot better than the wrench than was provided by the manufacturer. Why? Because the "cross wrench" worked a little like an impact wrench! Impact wrenches are very good at breaking loose a nut/bolt. Once a nut/bold is loose the pneumatic are very effective at spinning a nut/bolt off. A manual impact wrench acts like any other wrench. An electric impact wrench is likely to be on the slow side until the nut/bolt is quite loose. |

You break grade-8 lug bolts w/ no more than a 1/2" breaker bar routinely enough it's a problem???? I broke one many, many years ago. That one was enough to break me of the habit. I've no idea how many I may have damaged prior to that one, but it was probably more than none. In some 50 years I don't recall ever breaking a lug bolt on anything from passenger car to tractors and combines. Being as they're hardened and decent-sized diameters, I think it likely there was a fracture-failure already present to break one w/ just a simple bar (or, of course, you're undoubtedly able to apply much more of a lever-arm than I when applying same... ). I worry far more about the over-torquing of the average tire-shop grease monkey w/ the impact wrench on max at 150 psi over-stressing the bolt and/or stripping threads, not to mention warping brake rotors... |

12 volt impact wrench
Rear shocks, Chevy product. The bolt I broke was the main one coming
from the frame. I twisted the nut (3/4 or about that size of socket) and the bolt broke off. Looked like it would make for a LOT of work to replace that large a bolt, and not designed to be replaced. Not sure what the hardness was, but the broken bolt was supposed to take the force of the shock absorber. I know what you mean about the repair garage guys and their over active impact wrenches. I got a safety inspect one year, and came home. Figured to try the lugs, see if.... yep the only thing I owned that would loosen them was a 25 inch breaker bar. I get funny looks when I tell the repair garage to put the lugs on finger tight, and I'll set the torque before leaving the parking lot. -- Christopher A. Young You can't shout down a troll.

I don't need to jump on it,either.You can generate more torque by lifting up on the breaker bar/lugwrench then trying to push down on it with your weight. Is "G" suggesting you use the tire jack to lift up on the lugnut wrench to break loose the lugnuts? A great opportunity to have the thing slip and go flying with some force in a random direction. -- Jim Yanik jyanik at kua.net |

Good luck keeping the tool on the lugnut while trying that trick. The chances of that trick working on an overtorqued lugnut are about zero. |

Most of the stock irons put a sideways torque on the lug and the iron slips off, rounding both. Having a 3' hunk of blackpipe in the car is still a better solution, though. Having a good (cross) tire iron; priceless. A good cross type tire iron won't generate enough torque. Nowadays I always keep a 20-24" breaker bar and a 1/2" socket in the car. I can put a *lot* of torque on a lug with a cross lug-wrench. Stand on one end while lifting the other puts a tun on torque on the nut, while making sure there is no lateral torque on the lug.nut/wrench. I was talking about situations where the lugnuts have been overtorqued by a impact hammer. |
