Abstract
The invention is a wrenching tool useful for installation of the frangible, or torque-limiting, fasteners which are commonly used in the aerospace industry. The tool has a head with a post that is seated in the wrenching ring of fastener and is pivotally mounted on the jaw end of a handle. The jaw end of the handle moves towards the post as the handle is pivoted on the head, and grips against the outside wall of the wrenching collar. If necessary, the wrenching tool is used with a hex key wrench to immobilize the fastener bolt during removal or application of the frangible fastener.
