The easily adjustable torque screwdriver has a range of 5.00 in-lb to 40.00 in-lb with an easy to read scale. The cam-over design prevents over-tightening to avoid damaging components or fasteners. The body is of rugged construction with an all-aluminum casing. The internal mechanism is permanently lubricated. The Torque Screwdriver has a standard one fourth inch hex bit holder containing a strong rare earth magnet.
