One of the most confounding home improvement obstacles one can ever come across is a bolt or nut that has been screwed on so tightly in the past, using a wrench to unscrew it seems like a nigh impossible task. In fact, most people apply more pressure than is needed, stripping the bolt down instead. The GearWrench Electronic Torque Wrench helps prevent that situation by displaying the amount of torque your are exerting on the bolt via the display. It is capable of measuring the force used 2,500 times a second, buzzing and flashing green lights to let you know that you have reached the target torque. You will have to pony up $340 for this high-tech tool.
