From the Manufacturer Snap-on Industrial Brand JH Williams 3-Inch standard combination wrench has open and box ends. The super torque box opening design allows application of higher torque without rounding or deforming hex fastener points. No contact is made at the corners. Instead, wrenching forces are placed on the flat surfaces behind the points. May be used on all common hex, 6 point, fasteners with considerable advantage over conventional box end wrenches to increase both hand tool flexibility and economy. The box and open end openings are identical. It has a satin chrome finish.
