Double box end wrench offset

This offset box wrench set offers you a better grip on fasteners. All box ends are chamfered and broached, with 12 points of contact, for a tighter fit on corroded or damaged fasteners. Constructed of chrome vanadium steel, the wrenches in this box end wrench set are built for heavy use. Why are box end wrenches offset? In short, having the offset angle allows you to use the wrench in confined spaces as well as on flat surfaces. It allows for an increase in movement which creates a larger turning arc when space is a restriction. Even if you have all the space in the world, offsetting the wrench decreases the overall swing needed.
