An air powered wrench device with a pivotable head and associated method of using. The device comprises a handle pivotally attached to an arm. The handle comprises a housing, an air intake nozzle, an air driven motor, a drive shaft, a ball bearing collar, a universal joint, an on/off button, a trigger switch, a directional throw switch, a lock pin, a spring, and a pivot post. The arm is pivotally attached to the handle via the pivot post. The arm includes: an outer casing, an extension rod, a ball bearing sleeve, a first pawl gear, a second pawl gear, and a bit connector. The method of using the device comprises the steps of adjoining, affixing, aligning, allowing, enshrouding, getting, moving, obtaining, putting, rotating, shifting, squeezing, and tightening.

1. A method of using an air wrench device comprising the steps of:obtaining the device comprising:a handle, the handle including:a housing;an air intake nozzle attached to the housing, the housing having a distal end and a proximate end;an air driven motor attached to the proximate end of the housing, the air driven motor operatively attached to the air intake nozzle;a drive shaft operatively attached to the air driven motor;a ball bearing collar attached to the proximate end of the housing, the ball bearing collar operatively attached to the drive shaft;a universal joint operatively attached to the drive shaft;an on/off button attached to the housing, the on/off button operatively attached to the air driven motor;a trigger switch pivotally attached to the housing, the trigger switch operatively attached to the on/off button;a directional throw switch attached to the housing, the directional throw switch is operatively attached to the air driven motor, when the directional throw switch is slid into a first position then the drive shaft is enabled to rotate in a clockwise direction, when the directional throw switch is slid in a second position then the drive shaft is enabled to rotate in a counterclockwise direction;a lock pin slidably attached within a crevice in the distal end of the housing, the lock pin having an engagement head, when the lock pin is slid toward the proximate end of the housing then the lock pin is in an unlocked alignment, when the lock pin is slid towards the distal end of the housing then the lock pin is in a locked alignment;a spring attached to the housing and attached to the lock pin, wherein when the lock pin is in the unlocked alignment then the spring is in a compressed mode; anda pivot post attached to the distal end of the housing;an arm attached to the pivot post of the handle, the arm including:an outer casing having a distal end and a proximate end, the distal end of the outer casing having a cogwheel, the cogwheel is pivotally attached to the pivot post of the handle, the cogwheel having a plurality of flanges attached along the circumference of the cogwheel, each adjacent pair of flanges defining a corresponding recess between the adjacent pair of flanges, wherein the engagement head of the lock pin is insertable into anyone recess of the cogwheel, when the engagement head of the lock pin is inserted within anyone recess of the cogwheel then the arm is in a lock position relative to the handle, when the engagement head of the lock pin is not inserted within anyone recess of the cogwheel then the arm is rotatable about the pivot post;an extension rod operatively attached to the universal joint of the handle;a ball bearing sleeve attached to the outer casing, the ball bearing sleeve operatively attached to the extension rod;a first pawl gear operatively attached to the extension rod;a second pawl gear attached to the outer casing, the second pawl gear is operatively connected to the first pawl gear; anda bit connector attached to the distal end of the arm, the bit connector is operatively connected to the second pawl gear; anda protection skirt attached to the outer casing, the protection skirt is slidably attached around the distal end of the housing;affixing a pressurized air line to the air intake nozzle attached to the housing;getting a socket having a distal end and a proximate end;adjoining the proximate end of the socket onto the bit connector of the device;moving slidably the lock pin towards the proximate end of the housing into the unlocked alignment so that the engagement head of the lock pin is not inserted within anyone recess of the cogwheel wherein enabling the arm to be rotatable about the pivot post;rotating the arm into a bent alignment relative to the handle when the engagement head of the lock pin is not inserted within anyone recess of the cogwheel when the arm is enabled to rotate about the pivot post;allowing the spring to move the engagement head of the lock pin into one of the recesses of the cogwheel when the arm is rotated in the bent alignment relative to the handle, wherein locking the arm is in the lock position relative to the handle;enshrouding the distal end of the socket around a head of a threaded bolt when the proximate end of the socket is adjoined to the bit connector of the device and when the arm of the device is in the lock position relative to the handle;aligning the shank of the threaded bolt over the threaded hole when the distal end of the socket enshrouds the head of the threaded bolt;putting the directional throw switch attached to the housing into the first position so that the drive shaft is enabled to rotate in a clockwise direction when the shank of the threaded bolt is aligned over the threaded hole;squeezing pivotally the trigger switch so that the on/off button activates the motor when the distal end of the socket enshrouds the head of the threaded bolt, when the shank of the threaded bolt is aligned over the threaded hole, and when the throw switch is in the first position, wherein the threaded bolt is screwed into the threaded hole;shifting the directional throw switch attached to the housing into the second position so that the drive shaft is enabled to rotate in a counterclockwise direction; andtightening down pivotally onto the trigger switch so that the on/off button activates the motor, when the distal end of the socket enshrouds the head of the threaded bolt, when the directional throw switch is attached shifted to the second position, when the threaded bolt is screwed into the threaded hole, so that the threaded bolt screwed into the threaded hole is unscrewed from the threaded hole.
