ABSTRACT:
An apparatus for rotating a threaded tightening device includes a guide and an anvil utilized to impact a lug on the threaded tightening device to rotate the tightening device onto or off of a threaded member. The guide has a frame with a support sleeve attached thereto. A reciprocating device is received in and is supported by the support sleeve. The anvil is attached to the reciprocating device. When the reciprocating device is received in and is supported by the support sleeve, actuation of the reciprocating device will cause the anvil to repeatedly impact a lug to rotate the threaded tightening device in the desired direction.
