An apparatus to accomplish rotational work on a securing element. The apparatus has a main body portion and an articulating arm. The main body has a power source, a drive motor, and a drive shaft. The drive shaft extends into the articulating arm which has a first section rotatable about the drive shaft. The articulating arm also has a second section which is seated on a first transversely aligned drive shaft interoperating with the drive shaft itself. The first transversely aligned drive shaft transmits rotational work to a second transversely aligned drive shaft which supports a third section. A third section interoperates with a spindle section which receives the rotational work from the second transversely aligned drive shaft to accomplish rotational work on the securing element.
