Small tool replaces large torque wrench for turning locknuts. Preload tool "stretches" threaded rod on which locknut turns, reducing force on nut which can then be turned by common hand wrench. Advantages are reduced cost and weight, ease of manipulation in cramped space near actuators, and portability.
