URREA Box End Wrenches: URREA Wrenches 3/16 in. X 1/4 in. Open End Chrome Wrench 3016
Open end wrenches have two different sized ends on the same wrench and are one of the most common and versatile wrenches. The smaller the wrench end opening, the shorter the body of the wrench, and this is proportionate to the maximum leverage that can be applied to the head of the bolt or nut. By having two different sizes in a single wrench, the number of tools required for a job is reduced.
