I see an impact wrench in my future whether I understand the concept or not...

An impact wrench makes multiple very short and hard blasts within less than a second. This action, in MOST instances, allows the nut to be broken free without even moving the bolt. I've been using the rechargeable units since they hit the street for bedding and deck hardware projects and have yet to find a situation where it did not work.
If you have a bum thread that sticks or catches that would be an area where the impact wrench may not work and would spin the bolt. Do not over tighten as these things can snap a bolt clean off very quickly. I hit it with just a few short blasts.. Brrr. brrrr, brrr and that's it done!
