Abstract:
An open-ended wrench for turning a hexagonal object, the wrench comprising a handle and a wrench head disposed at an end of the handle; the wrench head forming a cavity defining an axis about which the wrench is to be rotated to turn the hexagonal object, the cavity being closed at a rear end thereof and open at a front end thereof; the front and rear ends being spaced apart in a direction extending laterally of the axis; the front end dimensioned to enable the wrench to be slipped onto and from the hexagonal object through the front end; the wrench head including first and second jaws forming a first front impact point and a second front impact point, respectively; the first and second jaws also forming a first rear impact point and a second rear impact point, respectively; the second jaw further including an outer impact point spaced from the second front impact point in a direction toward the front end of the wrench; a recess formed in the second jaw between the outer impact point and the second front impact point; the wrench being operable to receive the hexagonal object in a first orientation relative to the cavity, wherein each of the first and second front impact points is disposed to contact a respective side of the hexagonal object at a first distance from a nearest end thereof for turning the object in respective directions while the object is disposed substantially in the first orientation relative to the cavity; the wrench being further operable to receive the same hexagonal object in a second orientation, offset by 30 degrees from the first orientation, wherein a corner of the object is received in the recess, and each of the first and second front impact points, and the outer impact point are disposed to contact respective sides of the object at a second distance from the nearest end thereof; the first distance being of the same length as the second distance.
