Proto J1731 Box End Wrench, Satin, 5/8 inch 3/4 inch Head Size, 7 1/4 inch Overall Length, Offset

Proto Box End Wrench J1731

These half-moon-shaped box-end wrenches feature a crescent-shaped handle, allowing access to fasteners in tight spaces that cannot be reached with a straight-handle wrench. Double-end wrenches have a different SAE (inch) size on each end for use on two different-size fasteners. The enclosed head on each end of the handle provides more contact with the fastener and allows for more torque than an open-end wrench, as the box end is less likely to slip off the fastener.
