A 1/4" (6.4 mm) square drive torque driver that employs a patented torsion bar design to measure the actual twist of the drive, maintaining 2% accuracy across a 19.2 to 96 oz-in range. This mechanism connects the drive directly to the dial so that hand-hold position does not affect the reading, unlike standard lever-principle wrenches. Additionally, the 8-7/64" (206 mm) tool includes a tapered nose for easier access when working in restricted areas.
