Variants on this design have the short end inserted in a transverse handle, which may contain multiple keys of varying sizes that can be folded into the handle when not in use. Some lesser known hybrid drivers include striking wrench tools with square drive, and hydraulic impact wrenches (typically powered by on site hydraulic power such as present with military tanks, and many rail car applications). Previous page. The most common shapes are called open-ended spanner and ring spanner.The term wrench is generally used for tools Breaker bars are used to break loose tight fasteners because their additional length and strength allows the same amount of force to generate significantly more.
