    help me loose bolts
    This common types of air wrenches has plenty of torque. I use this cordless impact wrench to loose suspension bolts and other hard to remove fasteners. Makes removing large bolts easier especially when it is difficult getting a breaker bar to access the bolt. Not completely metal, but still feels sturdy.
