Abstract
An open-end wrench for turning a hexagon object has a wrench head formed by first and second jaws. The first jaw includes a first front impact point. The second jaw includes a second front impact point and an outer impact point spaced forwardly from the second front impact point by a recess disposed in the second jaw. A hexagonal object can be inserted into the wrench in a first orientation wherein first and second parallel surfaces of the object are disposed parallel to the first and second jaws and wherein the first and second front impact points are arranged to contact respective side surfaces of the object at locations spaced by a first distance from a nearest end thereof. After being turned by the wrench, the object is reinserted into the wrench at an orientation offset by 30 degrees from the previous orientation, with a corner of the object disposed in the recess. The first and second front impact points are arranged to contact respective sides of the object at locations spaced by a second distance from the nearest end thereof. The second distance is of the same length as the first distance.
