Claim:
1. A hand wrenching tool for removing installed collars of torque controlled or frangible fasteners, comprising: a first elongated handle providing a grip at one end thereof and a socket head at a generally opposite end thereof, the socket head defining a cavity having a through aperture and configured to receive a collar of the fastener therein and having an interior wall defining a plurality of teeth; and a second elongated handle pivotally connected to the first elongated handle by a connector extending downwardly from a top surface of the first elongated handle, and having a grip at one end thereof and a jaw at an opposite end thereof having a collar engaging cam surface; wherein the socket head comprises a generally semi-cylindrical wall that extends downwardly away from the top surface of the first handle at said opposite end at an angle of between 45 and 90 degrees, and is of a length or size to elevate the handle with respect to a work surface to provide create a hand gripping clearance space between the work surface and the gripping portions of the first and second handles when the socket head is placed over the collar of the fastener; wherein the first handle and the second handle are adjustably connected to one another to permit the distance between the teeth and the jaw to be varied to accommodate collars of different sizes; wherein upon pivoting the grips of the first and second handles towards one another, the cam surface of the jaw increasingly projects into the socket and pushes the collar of the fastener into engagement with the socket teeth and facilitate the removal of the collar from a threaded pin of the fastener as the hand wrenching tool is manually rotated.
