Abstract: A pneumatic tool is provided having a housing with an exhaust passageway and a handle. The handle has an inlet that receives the housing, an outlet having at least one exhaust port, and an interior surface that defines an exhaust chamber. The exhaust passageway, exhaust chamber, and the at least one exhaust port are sequentially in fluid communication when the housing is inserted into the handle. A seal disposed between the interior surface of the handle and the housing, the seal being located between the exhaust chamber and the inlet. Also provided is a handle substrate with an inlet that receives the housing and an interior surface that defines an exhaust chamber. The exhaust chamber is in fluid communication with the exhaust passageway when the housing is inserted into the handle. An endcap is removably attached to the handle and has an outlet with at least one exhaust port in fluid communication with the exhaust chamber. A seal is disposed at an interface between the handle and the endcap.

Abstract: A system and method for precision fastening of a fastener. The fastening system includes a motor and a sensor that provides a feedback signal from the motor to a controller. The controller compares the feedback signal to a threshold value to determine if an error condition exists. If the error condition exists, the controller oscillates a rotor to the motor between a first and a second position. In one construction, a resolver provides a signal to the controller representing a position of the oscillating rotor. The oscillating rotor vibrates the housing, thereby alerting an operator of the error condition. In one construction, the fastener device can alert the operator that the fastener is not tightened to a proper torque, and that the fastener is not rotated through a proper angle of rotation.
