Features Wrenches in these sets are double open-end wrenches with a head at each end that grips and turns SAE (inch) fasteners of a specific size. They allow access to fasteners from the top and side compared to box wrenches that can only access a fastener from the top. Wrenches may have a different head size on each end to fit different-sized fasteners, and they may have a different opening angle on each end to provide clearance around obstacles.
