ABSTRACT:
A wrench for turning a gas tank yoke set screw having a transverse torque bar about a set screw axis to selectively mount the yoke on a valve body and dismount the yoke from the valve body. The wrench includes a wrench head including a face having an elongate groove extending along a central longitudinal groove axis between opposite first and second ends of the groove for receiving the torque bar. The groove has opposing side walls extending generally parallel to the central longitudinal groove axis between the first and second ends of the groove and is spaced apart by a distance generally equal to a width of the torque bar so that the groove engages the torque bar when the torque bar is received by the groove. The side walls extend inward into the wrench head from the face to a groove bottom. The wrench further includes an elongate wrench handle extending outward from the wrench head to provide a torque arm for turning the wrench head when the torque bar is received by the groove and thereby turn the gas tank yoke set screw about its axis to selectively mount the yoke on a valve body and dismount the yoke from the valve body.
