IQv cordless impact wrenches from Ingersoll Rand develop roughly 360 ft-lb of torque and can remove about 120 bolts tightened to 200 ft-lb of torque in a single charge. Most NASCAR teams use the company's Thundergun pneumatic impact wrench for tire changes during pit stops.


After using prototypes of the wrenches for a few weeks, technicians with Evernham Motorsports, Statesville, N.C., suggested adding an extended anvil for hard-to-reach bolts. They also wanted a battery-charge-level meter.

Armed with this information, IR engineers expedited development of an extended-anvil option. Feedback on the charge meter led to making it a standard feature on all lithium-ion batteries.
