This citation summarizes a one-page announcement of technology available for utilization. A special wrench unscrews smooth-surfaced or damaged fasteners that cannot be gripped by a conventional wrench. It can be used in tight spaces and, in contrast to other tools and techniques, will not damage adjacent structures. The new wrench was originally developed to remove commercial two-part nuts that have a round body and a hexagonal cap. The new wrench consists of a central handle and two independent jaws with serrated teeth. To use it, the serrated jaws are placed on the fastener to be removed, and the handle is rotated until its teeth grip with a positive locking action. Rotatin of the wrench handle safely removes the fastener. ...FOR ADDITIONAL INFORMATION: Contact: Director, Technology Transfer Division, P.O. Box 8757, BWI Airport, MD 21240. Refer to MSC-18772.
