Abstract: An impact tool for removing bolts includes axially aligned impact section, torque section and shaft. The shaft is configured to extend through a socket to abut a bolt head when the socket is in operative communication with the bolt head. The shaft is additionally configured such that a torque applied to the shaft is transferred to the socket. The shaft defines a shaft face that abuts the bolt head. The impact section defines an impact face on the opposite end of the tool from the shaft face. The torque section is configured such that a torque applied thereto is transferred to the shaft. Accordingly, a blow to the impact face transfers an axial force to the bolt at the interface between the bolt head and the shaft face. Such axial force may tend to break a corrosive bond between the threads of the bolt and the receiving surface. Thus, axial blows to the tool in combination with torque applied to the torque section may tend to loosen and remove frozen bolts.
